In this episode, psychologist Per Espen Stoknes discusses his book: What We Think About When We Try Not to Think About Global Warming.


Common sense used to dictate that men and women should only come together for breakfast and dinner.

According to Victorian historian Kaythrn Hughes, people in the early 19th Century thought the outside world was dangerous and unclean and morally dubious and thus no place for a virtuous, fragile woman. The home was a paradise, a place for civility, where perfect angelic ladies could, in her words, “counterbalance the moral taint of the public sphere.”

Hypothetical situations involving dragons, robots, spaceships, and vampires have all been used to prove and disprove arguments.

Statements about things that do not exist can still be true, and can be useful thinking tools for exploring philosophical, logical, sociological, and scientific concepts.

The problem is that sometimes those same arguments accidentally require those fictional concepts to be real in order to support their conclusions, and that’s when you commit the existential fallacy.

Here is a logic puzzle created by psychologists Daniel Kahneman and Amos Tversky.

“Linda is single, outspoken, and very bright. She majored in philosophy. As a student, she was deeply concerned with the issue of discrimination and social justice, and also participated in demonstrations. Which of the following is more probable: Linda is a bank teller or Linda is a bank teller AND is active in the feminist movement?”

In studies, when asked this question, more than 80 percent of people chose number two. Most people said it was more probably that Linda is a bank teller AND active in the feminist movement, but that’s wrong. Can you tell why?

We often overestimate and overstate just how much we can learn about a claim based on where that claim originated, and that’s the crux of the genetic fallacy, according to the experts in this episode.

The genetic fallacy appears when people trace things back to their sources, and if you traced back to their shared source the ad hominem attack (insulting the source instead of attacking its argument) and the argument from authority (praising the source instead of supporting its argument), you would find the genetic fallacy is the mother of both kinds of faulty reasoning.

You might be in danger of serially committing the genetic fallacy if your first instinct is to ask where attitude-inconsistent comes from once you feel the twinge of fear that appears after a belief is threatened.

Without realizing it, you sometimes apply a double standard to the things you love, believe, and consider crucial to your identity.

If you do this while arguing, it is sometimes called special pleading. You search for exemptions and excuses for why a rule or a description or a definition does not apply to something that you hold dear while still applying those standards to everything else.
