THUNK – 95. Duverger’s Law & Ingroup Bias

This election is divisive, both in & between parties. Unfortunately, our brains don’t work too well in groups.

Evidence of an increasing division between political parties in the US –

Tajfel et al’s 1971 paper demonstrating that even totally arbitrary grouping does weird stuff to human brains –

Evidence that we show greater affinity for ingroup members who promote the group’s distinctiveness over those who try to be more evenhanded –

A study showing that simply framing a political argument as coming from the ingroup increases its acceptance dramatically –

Groups also make us prone to riskier behavior, arriving at more extreme conclusions together than we would on our own –

THUNK – 93. Mathematics: Discovered or Invented?

Is mathematics discovered or invented? Is it the language which encodes the cosmos, or an imaginary human tool? Does mathematics, in its pure abstraction, tap the inherent nature of the universe…or is it just our imagination? In the longest THUNK video yet, we dive into the metaphysics of mathematics, & the seemingly unanswerable questions therein.

THUNK – 83. CRISPR & Genetic Engineering

CRISPR is making big waves in biology, and for good reason; the doors to genetic engineering are now wide open.

QUICK ADDENDUM: The CRISPR method is currently only used to modify germline genomes (fertilized eggs), not fully-grown organisms. (That’s why I stress the “new humans” angle.) We have methods to achieve that sort of modification (viruses mostly), but CRISPR just lets us rewrite one DNA at a time really really efficiently.

SECOND ADDENDUM: I said in this episode that high IQ is correlated with depression. This is a highly contentious statement, with no compelling evidence. However, there are good reasons to believe that high IQ is related to bipolar disorder:
