A short talk about gender balance and sexism in
computer science.

11. What is this talk, really?
These are my personal opinions, not based on School
or University policy
Not a part of CS1002 in any sense, just something I
think you should be exposed to

12. The Computer Scientist
and the Cleaner
• Let me tell you a story.
“The computer scientist and the cleaner had
a long and happy marriage. One of their few
arguments was when she forgot their
wedding anniversary. But their marriage was
strong and he forgave her.”

13. The Computer Scientist
and the Cleaner
“One of their few arguments was when she
forgot their wedding anniversary.”
• Let me ask you a question.
• Who forgot the anniversary?
• Was it the computer scientist or the
cleaner?

17. Who forgot the
anniversary?
“The computer scientist and the cleaner had

• Look inside your brain
• Did you think the woman was the
cleaner?

18. A short history of
sexism in St Andrews
• The University is 600 years old, yet ...
• Its first female professor was a computer
scientist!
• Prof Ursula Martin MBE, now at QMUL
• Yes, a 600 year old University’s first female
professor hasn’t retired yet!
• For 579 years we didn’t have a female Prof
• Until 2004, the Rules of Golf for women were
made by a male only club in St Andrews
• For 595 years we didn’t have a female Principal
• Prof Louise Richardson

23. Let’s be clear...
• The University of St Andrews does not have
sexist hiring policies
• We have clear non-sexist hiring policies
• http://www.st-andrews.ac.uk/hr/edi/inclusiverec/
• The gender balance in St Andrews CS
• reflects general imbalance in the discipline
• and it’s a big problem

24. The most important
problem for computing
Sunday, 6 October 13

25. Why the most important
problem?
There are many TERRIBLE reasons for having
more women in computer science.
I only know of two good ones, but they are
overpoweringly good.
Sunday, 6 October 13

26. Why the most important
problem?
I only know of only two good reasons why
we should have more women in CS, but they
are overpoweringly good.
• It’s right
• Computer Science would be better
Sunday, 6 October 13

27. But is it a problem now?
• In the past this was a problem
• And it still is
• An almost random example
• Science faculty’s subtle gender biases favor
male students
• Proceedings National Academy of
Science, USA, 2012
• http://www.pnas.org/content/early/
2012/09/14/1211286109
• The change from the past is that gender
biases are now subtle
In addition to determining whether faculty expressed a bias
against female students, we also sought to identify the processes
contributing to this bias. To do so, we investigated whether
faculty members’ perceptions of student competence would help
to explain why they would be less likely to hire a female (relative
to an identical male) student for a laboratory manager position.
Additionally, we examined the role of faculty members’ preex-
isting subtle bias against women. We reasoned that pervasive
cultural messages regarding women’s lack of competence in sci-
ence could lead faculty members to hold gender-biased attitudes
that might subtly affect their support for female (but not male)
science students. These generalized, subtly biased attitudes to-
ward women could impel faculty to judge equivalent students
differently as a function of their gender.
The present study sought to test for differences in faculty
perceptions and treatment of equally qualified men and women
pursuing careers in science and, if such a bias were discovered,
reveal its mechanisms and consequences within academic sci-
ence. We focused on hiring for a laboratory manager position as
the primary dependent variable of interest because it functions as
a professional launching pad for subsequent opportunities. As
secondary measures, which are related to hiring, we assessed: (i)
perceived student competence; (ii) salary offers, which reflect
the extent to which a student is valued for these competitive
positions; and (iii) the extent to which the student was viewed as
deserving of faculty mentoring.
Our hypotheses were that: Science faculty’s perceptions and
treatment of students would reveal a gender bias favoring male
students in perceptions of competence and hireability, salary
conferral, and willingness to mentor (hypothesis A); Faculty gen-
der would not influence this gender bias (hypothesis B); Hiring
These results support hypothesis A.
In support of hypothesis B, faculty gender did not affect bias
(Table 1). Tests of simple effects (all d < 0.33) indicated that
female faculty participants did not rate the female student as
more competent [t(62) = 0.06, P = 0.95] or hireable [t(62) = 0.41,
P = 0.69] than did male faculty. Female faculty also did not
offer more mentoring [t(62) = 0.29, P = 0.77] or a higher salary
[t(61) = 1.14, P = 0.26] to the female student than did their male

(P < 0.001). Scales range from 1 to 7, with higher numbers reflecting a greater

• Male students were
ranked higher in
everything
• The only difference
between the male and
female students was the
names on CVs

28. The lowest difficulty
setting there is
John Scalzi, http://whatever.scalzi.com/2012/05/15/straight-white-
male-the-lowest-difficulty-setting-there-is/
• It’s really hard for straight white men to
understand the problem
• sadly it’s really easy for women to
• John Scalzi came up with a brilliant analogy
• Being a straight white male is the lowest
difficulty setting there is in the game of life
“You can lose playing on the lowest difficulty
setting.The lowest difficulty setting is still the
easiest setting to win on.The player who
plays on the “Gay Minority Female” setting?
Hardcore.”

29. What can we do?
• We can’t change today the gender imbalance
• We can make CS a much nicer place for women
to be
• We can do three simple things
1. Don’t be a jerk to women in CS
2. Don’t use sexist language
3. Understand that it’s not you who decides if you
are doing 1 or 2.
Sunday, 6 October 13

30. Don’t be a jerk
• This is really simple to understand
• Unfortunately being a jerk to women in CS
is really widespread
• (I mean in the world, not St Andrews)
• I’m not going to provide examples
• it would take too long
Sunday, 6 October 13

31. Don’t use sexist
language
• I mean this in two ways
• Don’t use language that implies CS people are men
• leads to the Computer Scientist and the
Cleaner
• leads to females feeling excluded
• and subtle biases as in the PNAS paper
• Don’t engage in sexist “banter”

32. Flip a coin!
• Need a user in your report?
Should she be a female or
should he be male?
• Do what I did once...
• Use FLORIN-66!
• Fast Location Of Random
Integral Numbers
• My best backronym ever!
• do wish it was FLORBN
though (Binary) image http://onewebby.com
This is a 1966 florin, a pre-decimalisation coin

33. The Hofstadter Analogy
• If you’re not sure if language is sexist...
• ... swap men and women for black and white
• If the result is obviously racist
• ... the original was probably sexist
• A St Andrews example...
• Was it ok that a male only club made the rules of golf, including
for women?
• Would it have been ok that a white only club made the rules of
golf, including the rules for black people?
• I learnt this from:
• “A person paper on the purity of language”
• Doug Hofstadter

34. You don’t get to
decide...
3. Understand that it’s not you who decides if you are doing 1 or 2.
• This is really hard to understand
• Maybe you think somebody shouldn’t be offended when they tell
you they are
• Tough! Guess what, they were offended!
• You only have two options
• “I’m sorry, but I deeply believe that X is true so I stand by
what I said”
• “I’m sorry, I’ll try harder not to say things like that in future”
• Never say “Hey, it’s only banter”
Sunday, 6 October 13

35. It’s not “banter”
• "Banter" is apparently a free pass: I can insult you, but you're not
allowed to be insulted, because "it's only banter". I can be
obscene, but you can't be offended, because "it's only banter".
No. If you're a grown-up, you know that your offensiveness may
offend, and you either accept that or you apologise and don't do
it again. Saying "it's only banter" makes you not only an idiot, but
an idiot who can't take responsibility for his own jokes.

36. Allies
• We need male computer scientists to be
“Allies”
• Men who think it’s important that both
women and men are treated right in
Computer Science

37. Not just gender
• I’ve focussed on gender today
• But same could be said for disability, people
with mental health problems, race, sexual
orientation, age...
Sunday, 6 October 13

38. Do not get me wrong...
If you are a male (straight white or otherwise), ...
I want you to have a fabulous time at St Andrews
I want you to get a first
I want you to have an amazing career in or out of computing
I just want the same for women and other groups at a disadvantage
And I want us all to work towards them not being at a disadvantage
