When we crafted that phrase, it was because we saw a similarity with physical fitness. If you work out today, you don't return home and declare, 'Great, I'm finished, I never have to exercise again.' Staying fit requires ongoing commitment. In the same vein, we've discovered that those with the strongest social bonds are the individuals who diligently nurture them.

You cannot understand entrepreneurial activity without understanding optimism. Research has shown that optimism and overconfidence in individuals is directly linked to their engagement in entrepreneurial activity.

It's been a high-speed laboratory for the most advanced electric cars in the world, which Formula E cars are.

Rape is one of the oldest weapons of war and it remains so to this day. For so long, it has been viewed as an 'unfortunate' side effect of war. But really, it is a tactic.

Politics is not about management – it's about creating a narrative that can inspire and can bring people along in a certain direction.

Markets are human artefacts; however we often treat them as natural phenomenon in the same way we might treat a language. People are the ones who ultimately make language, but we feel have no control over it as it's such an emergent phenomenon. Markets are emergent phenomenon too, but individual market-places have proprietors and groups of users and therefore markets are more amenable to change. When something isn't working, we can change the rules!

I'm advocating for a right to cognitive liberty, a new international human right that would be the right to self-determination of our brains and mental experiences.

The policies they prescribe are a continuation or exaggeration of the previous policies that created the structural problems in the first place.

If someone consistently films artillery strikes from their home, not only can we geolocate where the strikes are occurring, but we can also pinpoint the filmer's residence. If an unfriendly state actor would rather not have such footage made public, they could easily direct their artillery towards the identified filming location. This situation underscores the importance of witness protection.

When global markets open up, if you're selling t-shirts in the US or Denmark, you're disadvantaged because countries like Bangladesh produce them more efficiently and cheaply. This has fuelled arguments advocating caution when it comes to free trade. We've conducted what is, to my knowledge, the first study attempting to quantify both the benefits and costs of trade, rather than focusing solely on the benefits.

They help us to understand that there is no 'us' versus 'them', and that 'The Other' is, in fact, my brother, my sister; the other is me.
