The Most Hazardous Species: Us?

Question: What keeps you up at night? 

Richard Wrangham: I think that I'm still very bothered by the fact that humans have not taken on board the degree to which we are a dangerous species. There's a very wide sense that -- the default conditions for humans is if no bad person comes along we'll all live in peace together. I'm kept up at night by the notion that that's a dangerous concept because it underestimates the propensity for things going wrong. And I'm hoping that, just as more and more people understand evolutionary theory and where we come from and be real about us in that way, more and more people will appreciate that we do have to take into account our aggressive propensities because when you do that, then you can design a safe world. Then you can recognize when danger is coming. So, just as people do recognize that men are dangerous as potential rapists and we take back the night and we don't allow people to have dark areas in cities where it's simply foolhardy for young women to walk alone. So life is safer if we recognize the dangers and anticipate them. And that way we've got a great future. 

Question: How do we recognize that? 

Richard Wrangham: Well in the same way that we are doing now. I mean, look what happened in Kenya in 2008. There was a contested election and something like 2,000 people died. And that could have turned into a Rwandan genocide. But actually there was huge intervention, and it was resented by the President of Kenya, but people slowly came in with a single voice and said, look, we recognize a tremendous danger here, we really care. They worked for an intense couple of months in particular, and what happens is, you end up with the President and the Prime Minster from the rival parties and they're working together. It doesn't mean that peace will always happen there, there may be further conflicts. But people are sensitive now to the dangers. And that's what I think is really important.

Leonardo da Vinci could visually flip between dimensions, neuroscientist claims

A neuroscientist argues that da Vinci shared a disorder with Picasso and Rembrandt.

Christopher Tyler
Mind & Brain
  • A neuroscientist at the City University of London proposes that Leonardo da Vinci may have had exotropia, allowing him to see the world with impaired depth perception.
  • If true, it means that Da Vinci would have been able to see the images he wanted to paint as they would have appeared on a flat surface.
  • The finding reminds us that sometimes looking at the world in a different way can have fantastic results.

Education vs. learning: How semantics can trigger a mind shift

The word "learning" opens up space for more people, places, and ideas.

Future of Learning
  • The terms 'education' and 'learning' are often used interchangeably, but there is a cultural connotation to the former that can be limiting. Education naturally links to schooling, which is only one form of learning.
  • Gregg Behr, founder and co-chair of Remake Learning, believes that this small word shift opens up the possibilities in terms of how and where learning can happen. It also becomes a more inclusive practice, welcoming in a larger, more diverse group of thinkers.
  • Post-COVID, the way we think about what learning looks like will inevitably change, so it's crucial to adjust and begin building the necessary support systems today.
