Let’s go ahead and insert the “studies say” caveat, but there’s a lot of interesting stuff here. Selections:
“All _____ people look alike”
For all of us, whenever people are a different race it’s harder to tell them apart.
“The light that burns twice as bright burns half as long”
“You can tell a lot about a man by his handshake”
Absolutely. “Results showed that HGS was correlated with SHRs, aggressive behavior, age at first sexual intercourse, and promiscuity in males but not in females. HGS appears to be an honest signal for genetic quality in males.”
“Happy wife, happy life”
When the husband is happier than the wife, couples are more likely to divorce.
“Attractive women make men stupid”
“It’s the booze talking”
No, actually, that’s you talking.
“Spanking is bad for kids”
Kids who were spanked behave better as teenagers.
