The Science Behind Bisexuality: Why It's More Common Than You Think

The Science Behind Bisexuality: Why It's More Common Than You Think

Dr. Julia Shaw, a psychologist and author, discusses the science of bisexuality, including its history, common myths, and the importance of inclusion. She explains that bisexuality is a natural and common sexual orientation, often misunderstood due to historical biases and lack of research. The episode covers the origins of the term, the role of bisexuality in the LGBTQ+ movement, and the need for better representation and understanding.

If you think of the history of pride marches, one of the key organizers of the very first pride march was an openly bisexual woman in the United States. From the beginning, by people weren't just sort of around, but they were actively involved in queer liberation in the fight for gay rights, even though it took till the '9s to include the bee in LGBT. Hello and welcome to Instant Genius, brought to you from the team behind BBC Science Focus. I'm Jason Goodger, commissioning editor at BBC Science Focus. In today's episode, we're joined by Dr. Julia Shaw, a broadcaster, best-selling author, and psychologist

based at University College London to talk all about the history and science of bisexuality. So, Dr. Julia Shaw, welcome to the show. Hi, thanks so much for joining us. Happy to be here. So, today we're talking about bisexuality. So perhaps you're best known amongst other things anyway as a criminal psychologist, but over the last several years you've become a prominent voice in bisexuality research. So what led you to take this on as it's quite a shift from studying crime and criminals? It is. I am bisexual and I wanted to know about whether or not bisexuality had been studied empirically because I wanted to know what it was like for

people like me and whether there are some issues that I have or concerns, thoughts that I have that are shared with other people. And so I initially was hoping that I just sort of go to the bookstore and buy a book. And I realized quickly that book didn't exist and that there are anthologies and there's some excellent anthologies. There's some excellent um general research and writing on queer identities and queer people, but there wasn't anything specific to bisexuality. And so I decided I wanted it to exist. And so I went back to university and did a master's in queer history at Goldsmith University. and I founded the bisexual research group which is now an organization that has an annual international conference and there's

about 500 people who usually come to the conference to share their ideas and research from various fields on bisexuality. So let's first make it clear exactly what we mean by bisexual. So rather than simply meaning a person that's attracted romantically or sexually to a cis man or a cis woman both. It's actually more of an umbrella term, right? Yeah. So, by the way it was originally used and this is where having that foundation history has become really useful for me and going back and reading up on some of the earliest scholars who wrote about bisexuality and used the term. And if you trace the term back to people like Havlock Ellis, who was one of the first people to use the term in writing, he used it to describe

people who are both as in biexual, both homo and heterosexual. And so these terms homo and heterosexual had come up earlier when a and this is one of my favorite facts is that the term homosexual as in same attraction to the same gender was coined by a gay scholar who wanted to fight for the rights of gay people of gay men in particular. And he needed to create a word for homosexuality but then he also needed to create a word for not homosexuality. Right? And so he called people who were straight heterosexual. So people attracted to others. So hetero being other than. And I think it's really funny that a gay man created heterosexuality. I think it's one of my

favorite facts about queer history that I don't know why this isn't on slogans everywhere. Um but the other thing that happened then is because we had these two terms quickly researchers were like wait but there's people who obviously are interested in men and women who are both homosexual and heterosexual. And so we are going to call these people bisexual. And just to be clear, it was both homo. So both same and other. And this is where it was never actually men and women technically. It was always same and other genders. And so as our concept of what gender means and how you know things like cis male, like that wasn't a term at the time, right? And so that how that has now changed. I

think a lot of bisexual people find that definition embraces that as well. So it's it's just I'm attracted to people of multiple genders rather than I'm attracted to men and women. Yeah. So I think one of the things with uh bisexuality is that often people are they're not necessarily hiding in plain sight, but they're not visible in a way that a lot of other queer people are. So do we have a sort of rough idea of the number of people that are bisexual? You know, maybe from census data or things like that. Yeah. So bisexuality has an invisibility problem in the sense that there is less of what's called a visual language. And so there's fewer ways to show that

you're bisexual than being queer in other ways often. And so when you ask by people, you know, how do you make yourself visible and like seen as a bisexual person? They kind of go, well, I kind of like integrate elements of sort of what lesbian people might wear or what gay men might wear. Maybe I add a rainbow. Maybe I add a bisexual flag. Um, but there isn't quite the same sort of obvious language. There can be. So I mean septum piercings for a while became for me like ah there's one of us. Um for before that it was cuffed jeans was a classic. Um not being able to sit in chairs was a stereotype for a while. I mean, there's been there's definitely also lots of jokes and by culture jokes, but um

even with me, like unless I say I'm by, especially because I'm my primary partner is a man, it's it reads as a straight relationship and I read as straight and that's partly just because of who I happen to be in a relationship with. And of course, I continue to be by no matter who I date or if I'm not dating anyone. And so that's something that a lot of by people say they face is that they constantly need to be that person who either says it out loud which feels annoying and you're like coming out over and over again or you need to lean in and then you might still get miscatategorized as lesbian in my case as a woman and so you're still not seen as by and so that by eraser can be an issue also

psychologically because we know that by people are less likely to seek communities queer communities partly because they don't feel like they're queer enough, but then they also don't feel straight enough for the straight communities. So you find that by people are compared to others least likely to be plugged into groups and so have more mental health concerns that come with being isolated from those communities. Yeah. So there's a lot of sort of certain stereotypes surrounding bisexuality which I think we need to get out of the way to be honest. So it's like some common ones are bisexual women are easy or kinky. bisexual men are just actually

homosexual. They just don't admit it to themselves, etc. So, you know, how can we get rid of these? Well, and that trans people can't be by. Ah, yeah. There's a lot of trans by people where it's like you can destabilize both gender and sexuality like you can, right? There's lots of mixes of things. Um, or that you can be I mean, obviously there's um people who are uh non-binary who are bisexual. So, I mean, there's there's lots of versions of that. And so I think to destabilize the stereotypes, one of the things is visibility. That's

why it's so important to I think to say that you're bisexual and to almost face the what still happens disproportionately I compared to other sexualities is that by people still get asked stupid questions like is one person ever enough for you? Or can you be monogamous? Are you going to be cheating? Are you are you going to want threesomes all the time? Are you going right? Like almost this like hypersexualized element and as you say for men it's more of a there's a bit of that hypersexualization potentially but there's more of the no it's probably a stepping stone to gay like you're probably actually gay and so I so making it visible and talking about it more and just making it more normal I think is going to be quite

a lot of the success that comes from visibility. But we're seeing that already. I mean, even since my book came out in 2021, there's been so many TV shows now that have a by character, and I think that will make a huge difference coming forward, sort of going forward. Yeah. So that would uh sort of queue in my next question quite nicely that um sort of a lot of people will use the narrative that it just doesn't seem to go away which is that bisexuality is a trend or you know perhaps even worse a phase. So you why do these myths persist? Uh the myths are I think mostly because we have in our minds something from childhood and beyond that the idea of the nuclear family really

and it's a man and a woman and some kids and at some point some people accepted that okay maybe it can be a man and a man or a man and a woman but the idea that it could be any other constellation continues to evade people and so bisexuality is and if you look at the history of this again and like how bisexuality is sat in various political movements, you see that we've been seen as the enemy from all sides. And so even queer people in the fight for equal marriage for example and for gay rights have at various points there's some really interesting correspondence in archives that I was going through as part of my masters and you can see how the correspondence is like we need the bisexuals to leave and

out of for especially out of women's spaces actually and so there was this the political lesbians and there were lesbians and women loving women spaces and the idea was that if the byw women are here they are the traitors they will go home and tell the which I think is really funny. Like even if they're dating one of us right now, they will leave and they could be traitors. And that it's it is a thing that I think still sort of sticks a bit where it continues to be a bit of a like iffy I don't really date by women. I mean, I've met people recently who still say I don't really do by women. And I go, well, that's that's a horrible thing to say.

Um especially in a queer space. And so I think until those stereotypes continue to soften, I think we still have quite long way to go. So sort of another idea that you often hear which is not quite per as pervasive as those other ones is that um I and I don't know where this comes from is that we're all born bisexual and then some somehow we sort of develop or grow out of it. You know where does that idea come from? Comes from Sig Freud. Ah okay. Yeah. the source of most of my the things I don't like about psychology. They're basically always back to Freud.

Um, yeah. No, Freud said that everyone's born bisexual and that you mature out of it into usually homosexuality first and then and then you're straight. And so obviously straight is the final goal the and uh that is again a horrible way of thinking about it even though sometimes it's misqued it as sort of Freud was a friend of the bias and it's like I mean that's not how I he saw it as a regressive sexuality. I'm not sure I would see that as positive. But if you look at the animal kingdom and you look at queerness and bisexuality specifically in the animal kingdom, there has been a real destabilizing of the idea that sort of animals have sex to reproduce. And that is that is sort of that biological

imperative that main thing that animals are using sex for is reproduction. And that is a thing that most animals use sex for. But lots of them also just like humans use it for other things. And those other things can be uh joy, affection, they can be um making a nest together, sharing responsibilities over for example child, you know, rearing children. And there already in the 1940s and 1950s a scholar called Alfred Kinsey who famously wrote about human sexuality as well. He said that all of these people who are going into nature, so he was a biologist and he was saying people who are going into nature and saying that all they can see is heterosexual behavior and everything else is dominance or something else

are wrong. They're just imposing society's human values onto animals rather than actually describing what they're seeing in nature. And he was saying that in the 40s and 50s. Now, fast forward to today and if you speak to anyone who works in a zoo and you say, "Are there by animals?" They're like, "Well, obviously." And the idea behind that, if you then go even deeper, is that well, you could say that actually bisexuality is the most flexible strategy. Like, if you were to choose a sexuality that is the most likely to sort of lead to reproductive success, if that's what you're aiming for, then bisexuality is pretty great because actually you're flexible. And so if there's a lot of men one year, a lot of women one year, a lot of boys or girls if we're talking about

like other species, um then you can adjust and survive and hopefully your species can better survive as well. So I think I'm not saying that this means that bisexuality is better than heterosexuality. It's just that I think we need to desenter heterosexuality and ask the same questions that we ask of queer lives and queer ways of living. And we need to ask the same questions of heterosexuality. And I think that changes a great deal about how we think we understand the world. So sort of having said that um you know would you say that our sexual identities are fixed throughout our lives or are they a bit more mutable? You know you often hear of you know you say you've got an uncle or whatever who's

who's happily married then suddenly like oh no he's gay you know. Is that a common thing? you know, can our sexual orientations, identities, well, maybe they don't change. Maybe our expression of them does I don't know. What do you think about that? I think sexuality is fluid. So, I think that across our lifespans and even in our own way of thinking about even day by day, we can have a different interpretation of who we think or know we are attracted to and also how that interacts with how we want to live our lives. Because it's one thing to be queer in London in my group right now where I can be by and I can live a polyamorous life and I have other friends who also do that and it's accepted and I don't face any violence.

But if I was somewhere else in the world then I might very well try actively not to be queer and to just live what looks like a heterosexual life even though that's not what I would choose. And so that but that's me also having grown up in a society where bisexuality was an option. Now if I didn't even realize that was an option or I always thought that it was sort of evil if quote unquote then I might go well obviously I'm straight because I'm attracted to men and that's enough. I would never second guess it and so I might never even develop this idea that I could be by or that I am by. So I think we need to it means a lot of different things, right? And I think there is something to be said for if you

are surrounded by people and stories that allow you to think about how you yourself want to structure your love life. I think that gives you the potential to really like open up to lots of possibilities. But if you're never given those narratives, it can it just changes how you're shaped in the first place. And then it could be that later on if you go into a to a different place or you're suddenly exposed to different ways of talking like we've seen language evolve. We've seen stories around homosexuality and querness evolve dramatically over my lifetime and you know you maybe you get divorced after 40 years and you go actually I am interested in men or actually I or I am interested in women

and you know I think that's where there's so many factors uh that almost like obviously people need to be able to I don't know understand in themselves that's a possibility That's often where I wanted to take it. It's it's not that I think everyone's sexuality can change at any time. It's more that I would like people to be open to especially the idea of being able to fall in love with people of any gender because love is so hard to find anyway that I like the idea that you could just be like maybe it doesn't matter which gender this person has. But that's a very by thing to say.

Sure. So let's have a look at some of the sort of bigname researchers. So you mentioned there Alfred Kenzie. So can you give us a sort of cliff notes of the kind of work that he did because it was quite a few years ago now. Yes, it was right in the post well pre-war period actually pre-world war ii and then postworld war II and Alfred Kinsey was doing research initially on gall wasps which are an insect and he was asked in the post-war period to study sexuality and families and he realized that in this in the 1940s that he didn't really have the answers to the questions his students had so they're like Alfred Kinsey you're a scientist go teach go teach about sex and so He

started doing research on what it means for humans to engage in sexual activities and he interviewed thousands of people. So one of the things about Kinsey that's that's special is he had a research team but he also personally interviewed thousands of people and he created something called the Kinsey scale. Y and the reason he created it is because very quickly into his research, he realized that when you ask people questions about who they're attracted to and uh you know and whom they've had sexual encounters with or fantasized about or fallen in love with or had relationships with that the idea that it was just heterosexual and homosexual that it didn't make any sense at all.

And so he created the Kinsey scale, which is from zero to six, from zero being exclusively heterosexual attraction to six being exclusively same-sex attraction and everything in the middle. So everything from 0.1, again, he's he's that kind of scientist, so he allowed for decimals. You could be 0, you know, 15. Um, so just tiny little bit, just a little whisper of queerness. Um, but you could also be like a three or four, right? Right. Somewhere in the middle and more classically by that you're more equally attracted to men and women or to people of same and other genders. And um, and I think that really shifted the conversation because he then using this scale found that about half of men are not exclusively

heterosexual or homosexual. So they're somewhere on the B spectrum. Half of men. Large number. That's so many people. The majority in fact. Yeah. Well, yes. Um or and about a quarter of women is what he found on in his research. So he did sexual behavior in the human male was one of the books he wrote where he summarized all this and then he wrote sexual behavior in the human female um along with the research team. The sexual behavior in the human female specifically also involved quite a lot of women none of whom were listed on the cover which frustrates me to this day. But so

so when you look at it initially it's just like sexual behavior in the human female and it's just like all these male names which yeah not a good look but I mean science right science in the 50s not a good look um but he did in fact have women on the team as well but he was finding that so 25% and 50% and he didn't mean that people identified this way just that he classified them that way based on the lengthy conversations he had that were structured interviews um and those books sexual behavior in the human male which came out I think in 1948 or 49 and then in the early 1950s sexual behavior in the human female they were both bestellers and this is something that is remarkable is that Kinsey sold out stadiums like

people really wanted to hear what this guy was saying and this guy was saying most of you are by basically and that is not what we think about when we think about the history of bisexuality we think of like you know maybe the hippies in the 70s maybe that was the beginning or maybe it's like now like I feel like everyone's buying now this is the kind of you still hear that right everyone's buying now what does that mean and according to Kinsey he's like well I mean in in the 40s and 50s everyone was also already buy so I think it's really important to have that context yeah so sort of another researcher a little bit later that sort of took the ball and run with it was um Fritz Klene.

Mhm. So, you know, what can we say about his sort of important insights? One of the reasons why Fritz Klein took the ball and ran with it is also because Kinsey died tragically young. So, he died I think even in his 50s and so he would have definitely kept researching and we probably would have had many more insights but he died quite young of a heart attack. Fritz Klein was doing therapy in the United States and he was particularly interested in helping people who were struggling with their sexuality and he found as a by man. So he was bisexual himself and he found that there was really not enough conversation about bisexual men and there wasn't anywhere to go and so people would be sent to therapy to like

not be gay or not be bisexual to get rid of their homosexual urges. and he wanted to create a space where people could talk about their bisexuality in particular and not be shut down. And so he created talking groups like therapy groups particularly for men at the beginning and they would talk about you know their relationship with you know how they were expressing their attraction to men and women and what that meant for them and how they were struggling through it or not. And he came up with the client grid. The client grid is an adaptation from the Kinsey scale where he still uses although he does one to seven I think. So he uses the same scale anyway um and he just shifts it up slightly but he um me measures things in past,

present and future and he measures it in uh different categories. So, for example, in the past, has your lifestyle been one where it's mostly same sex or mostly other sex? So, I mean, you could picture it in this way, sort of am I going to um mostly male or female spaces or in more of a culture sense, am I going to gay bars or am I not going to queer spaces? So am I living more of a heterosexual looking lifestyle or am I looking living more of a homosexual living lifestyle? And then if you take that in the past, the present and the future or ideal um it's you can sort of differentiate it up a lot more. And so basically what he was trying to do is to look holistically at people's identity, at their sexual attraction, at their romance, at

how they live their lives, and to rate everything to show here are some issues where you are actually not living what you think is your own ideal and here are maybe ways in which we can align the ideal and what's actually happening. Does that make sense? Yeah, absolutely. So just like out of interest if anyone listening thinks oh you know I'd like to see where I lie on that scale can we do it online? Yeah, there's you can go Klein grid the Fritz Klein grid um online. There's the Klein Institute which continues to exist even though Fritz Klein also has since passed away. But there's lots of ways of doing it. But I would encourage you to the Klein Grid over the Kinsey scale partly because the

Klein Grid asks you so many different questions. And for me, one of the things I realized when I was doing it is that initially I think I was having some frustrations in not being uh in enough queer spaces. So I was li I was by and I was happy with my bisexuality but I wasn't living it in a queer enough way and so I felt like I was almost like masquerading in these heterosexual places and that it was affecting me psychologically and so by doing this I identified that as actually I want to go to more queer spaces and so then I did and I mean that's also what happened with the book right is the book has taken me to so many different queer spaces now and it's so good for me as a person and

my identity to feel seen and to feel like, you know, there's there's place. And I think lots of people have that experience when they do the clangid. And the other thing that's fun about it is because it's not just like the Kinsey scale where it's like where are you on this scale now? It's past, present, and ideal. What you also have, if you give this to anybody, because you it's not this isn't just for queer people. This is for anybody. If you give us anybody, I've had quite a few friends coming back with the ideal being by, but they're actually straight. And I think that again is an important conversation to have that it's not just straight that people think of as the ideal. It can be

other things and that straight people can also be unhappy or frustrated with their sexuality, not just queer people. And so again, introducing nuance into that conversation. So, what things can we all do whether we're, you know, I don't know, bisexual, gay, straight, asexual, to like improve by inclusion? Oo, the best ways to improve by inclusion is to occasionally use the word I mean, I feel like now there's there's more conversations around trans people, which is great, but it's also great if you occasionally use the word by. So you could say this person is like if you see someone in a same-sex relationship for example as well, you could say this person is gay or by if you're not sure. And I think even just

introducing that I mean they might correct you but even just introducing that as an option I think goes a long way. And it opens up that possibility for people to go yeah no I am by and not just defined by the partner I'm currently dating. The other ways in which we can increase by inclusion is by having by people visible on panels. for example. So again, if we're thinking about like pride celebrations, making sure that as part of the visible representation on stages, on panels, on posters, on whatever it is we're doing, that we don't forget bisexuality because it is almost always still forgotten. And the problem is if it's never visible is it reinforces that idea that we're not really queer and we're we don't fit. This isn't

actually for us. And that is something that desperately needs to change because we know that the mental health risks for bisexual people are higher partly because they don't have that. And so opening up the community and being overtly inclusive is really important. And if someone if you're straight and someone comes out to you as by don't start with does that mean that you need to be polyamorous? That is I mean you can ask that question in a separate context in general of all your friends if you want because I mean sure straight people can also be polyamorous but don't assume that just because someone is by that they are more sexually promiscuous or more likely to be polyamorous because they aren't

necessarily and that is a separate conversation. So one thing that uh a lot of people probably don't know is that bisexuals have always been involved in the pride movement. Yeah, actually if you think of the history of Pride, so Pride marches, you can actually see that one of the key organizers of the very first Pride march, which was called Christopher Street Day, the Christopher Street Day parade, that was someone called Brenda Howard. And Brenda Howard was an openly bisexual woman in the United States. And I think it's really important to remember that from the beginning by people weren't just sort of around but they were actively involved in queer liberation in the fight for gay rights.

Even though it took till the '9s to include the B in LGBT, right? Yeah. So, if you look at sort of the history of where the letters all fit together, um there was a dispute around the by and that you could have lesbian by but you couldn't have lesbian and bisexual because they didn't want the word sexual in there which I think is really funny. Um so, and gay was okay, but homosexual was also bad. Um, and so we settled on by and so yeah, it was in the 90s that it really officially got added even though bisexuals have been there from the beginning.
