Length of ring and index fingers 'linked to sexuality'

Sample size of 18 and 'on average'. Scienceclickbait, you don't miss anything spectacular by skipping this article.

That's a very dismissive attitude. There are limitations with the study, but the methodology is sound.

Digit ratio is actually a very well studied effect. Hundreds of studies have been done on it.

The wiki page references at least 10-15 studies discussing its correlation with sexual orientation.

I can't figure out why this is news. What am I missing?

I imagine it must be difficult to find identical twins where one is gay and the other straight, but n=36 sure sounds like a small sample.

I would have imagined the uniformity in finger lengths between identical twins would be the limiting factor.

I'm surprised that it's even possible for identical twins to have different exposure levels to testosterone in the womb.

So seems it's not a social construction after all.
