A colleague sent me this - she is seething, and rightly so. I am too. Arrant fucking nonsense, and extremely sexist.

(Need to log-in to LinkedIn to see it unfortunately, but I'll put some 'highlights' below.)

MEN - did you know you have seven times more gray matter than women? And women have TEN TIMES more white matter than men? Well, you do now.

Did you know Gray matter is used for deep thought? And white matter connects stuff, right? So let's think... it must be good for seeing connections between things! Seriously.

Also ladies, your "anterior cortex" is slightly larger too. "This is the part of the brain that controls emotion and memory." Kill me.

Now some top tips. Make sure everyone is using their white AND gray matter during meetings.
I get this a lot, sometimes my gray matter is going like the clappers but my white matter has just popped out for a cheeky cigarette and I can't make anything connect. FFS.

Finally, ask for impressions AND facts, because "Sometimes it's hard for the female brain to express what they intuitively know." Jesus fucking tap-dancing Christ, what is this, the 1950s?

I've seen a lot of pseudo-science @neurobollocks, but this one is an absolute doozy. Added points for wantonly unreconstructed sexism too. A classic.
