Quotes from the show

I’m very, very concerned that North Korea today has an advanced biological weapons program.
You don’t need a lot of biological weapons to potentially kill billions of people…
Fortunately, while we’re not there yet, the science and the tools that are now available enable the possibility of making [such] bioweapons obsolete.
Andy Weber, former US Assistant Secretary of Defense

…they randomly determined when officers would take the training… so it’s a really nice natural experiment.
And they found that this one-day training program pretty dramatically reduced both complaints and use of force.
Jennifer Doleac, Associate Professor of Economics at Texas A&M University

…more teachers, more books, more inputs, like smaller class sizes – at least in the developing world – seem to have no impact, and that’s where most government money gets spent…
Rachel Glennerster, Chief Economist at the UK Department for International Development

I’m inclined to think that I can imagine a being with the ability to consciously think and perceive, but no ability to feel pleasure or pain.
And still, it just actually seems monstrous to me to think about killing such a being.
Dave Chalmers, Professor of Philosophy and Neural Science at New York University

A serious reasoning error that is particularly common among educated people is to argue that if a study hasn't been done on a particular question we have 'no data', and therefore no basis on which to form beliefs or act.
This is incorrect and dangerous. 1/

Octopuses are pretty nuts.
Totally separate evolution of intelligence — our nearest common ancestor was a worm or something. They're highly curious and learn the way we expect primates to do. But:
• They're not social, so intelligence didn't emerge for a social purpose. 1/

What could be the harm in temporarily pausing putting out the fire and getting the whole fire department to carefully check over its hoses for tiny leaks?
