I agree, Errol, and I think the nature/nurture thing is highlighted in the Edutopia article by the fact that 16 year olds show the effects of 10 years of 'nurture':
When asked to draw a scientist, 70 percent of 6-year-old girls draw a woman, while only 25 percent of 16-year-old girls do.
I'm surprised by this. The younger girls are presumably influenced by Mum as primary caregiver & most infant school teachers being women, but in my day that was combined with the idea '... and the men go out to work & do everything else'.
Older girls would see a lot of female scientists in documentaries on TV, surely? Maybe they don't watch them. Is it the influence of studying with boys? Or what they see in films?
I should probably read the article.😬
