In one line: Gender bias is research that treats one gender unfairly: as better, as worse, or as the default.
Imagine a study of how people cope with stress. It tests only men.
The report then says: "this is how people cope".
Half of humanity was left out, yet the finding is stated as if it fitted everyone.
Two words for it: Gender bias: one gender is treated unfairly in the research.
Androcentrism: a common form of it, where "male" quietly becomes "human".
Like other biases, it can enter at any stage: in who is sampled, in what is measured, and in how the results are read and applied.
Remember: Who was studied, and who was left out?

Key idea: Gender bias pulls in two opposite directions: it exaggerates differences, or it ignores them.
Alpha bias: exaggerates differences
- Treats genders as more different than they are
- Makes one gender look naturally better or worse
- Often turns a stereotype into a "fact"
- Claiming that women are built to care and men to lead
Beta bias: ignores differences
- Treats genders as more alike than they are
- Often by studying one gender only
- Then applies the findings to everyone
- Testing a medicine on men and giving everyone the same dose
The stress study shows beta bias and androcentrism. Only men were studied, possible differences were ignored, and the male pattern was treated as the pattern for all.
Exam tip: Decide the direction first.
Differences exaggerated: alpha bias. Differences ignored, or one gender treated as the norm: beta bias or androcentrism.

Key idea: Gender bias can change who is diagnosed, what the statistics show and which treatment is given.
Three places it shows
Diagnosis
The same problem can look different in men and women.
A depressed woman is more likely to describe sadness. A depressed man is more likely to show anger or to drink. A doctor looking for sadness finds it in her and misses it in him.
Prevalence statistics
Depression is recorded about twice as often in women as in men.
Part of that gap may be real. Part of it may come from who goes to a doctor and how doctors read the symptoms.
Treatment
For many years, new medicines were tested mostly on men.
Giving women the same dose assumes their bodies respond in the same way. That is beta bias, and it can make a treatment less safe.
Diagnosis · Statistics · Treatment
So a difference between men and women in the statistics has two possible sources: a real difference between them, or a difference in how they are assessed.
Watch out: Bias can work against either gender.
Women may be over-diagnosed with one disorder while men are under-diagnosed with the same one.
Key idea: Gender bias is reduced by studying all genders and by checking, not assuming, whether they differ.
Four ways
Balanced samples
Include all genders in fair numbers, so that no finding rests on one gender alone.
Report each group
Give the results for each gender separately. A real difference then shows up, and a difference that is not there cannot be assumed.
Fair measures
Check that a test or a list of symptoms works for each gender, and was not built from one gender only.
Question your own assumptions
Researchers ask themselves what they expect to find about men and women, and whether that expectation is shaping the study.
Balanced samples · Separate results · Fair measures · Own assumptions
The aim is not to say that the genders are the same, or that they are different. It is to let the evidence decide.
"We treat everyone the same": That sounds fair, but it can be beta bias.
If a treatment was only ever tested on men, treating everyone the same quietly disadvantages women.

How this is asked: Gender bias is asked as part of the concept bias: in a 15-mark essay set in a context, such as health and well-being, and as one of the concepts in the 15-mark question on a study you are given.
The essay pattern
- Say what gender bias is and which direction it takes.
- Give one or two clear examples, real or made up.
- Say what it does to diagnosis, to the statistics or to treatment.
- Give the other side: a real difference, or what reduces the bias.
- Finish with a judgement.
The trap: "it is sexist": That is an opinion, not an analysis.
Name the type, alpha or beta, say who was studied, and say what that changed.
In the context of health and well-being, discuss how gender bias can affect the diagnosis of mental health disorders.
