Controversial Views on Human Nature

Islamic suicide bombers are motivated by a lack of sex, says evolutionary psychologist Satoshi Kanazawa. The scientist has put forth some controversial views on popular topics.

Why do beautiful people have more daughters? Because beauty is more important for a woman than a man, according to evolutionary psychologist Satoshi Kanazawa. Why are most suicide bombers Muslim? Because they don't get enough sex. Why are liberals more intelligent than conservatives? Because liberalism is "evolutionarily novel." The London School of Economics researcher and author of Ten Politically Incorrect Truths about Human Nature is accustomed to defending his provocative assertions against outraged critics. ... "Like it or not, human nature is simply not politically correct," Kanazawa says.

Is this why time speeds up as we age?

We take fewer mental pictures per second.

  • Recent memories run in our brains like sped-up old movies.
  • In childhood, we capture images in our memory much more quickly.

Trauma in childhood leads to empathy in adulthood

It's not just a case of "what doesn't kill you makes you stronger."

Mind & Brain

  • A new study suggests children who endure trauma grow up to be adults with more empathy than others.
  • The effect is not universal, however. Only one kind of empathy was greatly effected.
  • The study may lead to further investigations into how people cope with trauma and lead to new ways to help victims bounce back.

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

Videos
  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
