"First of all, let's look at the correlation with a straightforward measure of whether women can be leaders, which was assessed by asking the level of agreement with two questions: “On the whole, men make better political leaders than women do” and “On the whole, men make better business executives than women do.”
Overall, there's a fairly good correlation. But there is an exception, and that's Asian countries. There are only a few Asian countries in the sample, so it's hard to draw sweeping conclusions. But they are all very sexist, whether their citizens are religious (Thailand, Taiwan) or non-religious (China, Hong Kong, Japan)
So I took these countries out of the analysis - in fact, what's shown in the graphic is only those countries with a predominantly Western, Christian culture (i.e. North and South America, Europe, and Australia).
In these Westernised countries there's a strong, linear relationship between religion and sexism.
In fact, if you narrow the sample a bit more to look only at European countries the fit is even cleaner (I haven't shown this, but it's a remarkably straight line)."
