We know this, but a lot of women today (and some men) buy into that supposed statistic.
And even progs like the Atlantic Magazine now admit it.
The bit of research on such doesn’t even show that, and it’s all likely highly flawed, anyway, what with the observation no doubt influencing what is observed; i.e. you tell people you want them to make a note of how often they think of something, they’re liable to think about it more than they otherwise would.
So the ‘science’ itself is unreliable.
Throw that in the face of the next woman or male feminist who tosses that false stereotype out there.
