It's the gorram cats!

It's all coming together, see. Toxoplasma gondii—the parasite that can only reproduce in cats, so it migrates into the brains of rats and convinces them to be more edible—can also infect the brains of humans, though it doesn't convince the humans to be more edible, no.

25% of Americans are infected. That's a significant number as you'll see.

So in Humans the Toxoplasma has gender differentiated effects. Here's what it does to men:

• makes men appear more macho
• makes men stupider
• makes men fear uncertainty
• makes men fear novelty
• lowers men's "superego strength" (disregards rules, expedient, shortened attention span, less responsible).

I.e. Toxoplasma Gondii turns men into neo-conservatives.

As for women, it's a little different:

• makes women more intelligent.
• increases women's superego strength.
• makes women more empathic.

There's no explaining Ann Coulter.
