There is a lot of misunderstanding about demography and one of the biggest misunderstandings is that it's destiny. If it's destiny, it is not that interesting to study, but it's not destiny.

Conditional on the emergence of the human brain, civilisation was inevitable for many reasons. We had a commendable population in Africa 300,000 years ago and given the fact that these individuals were equipped with the power of the modern brain, the emergence of civilisation was inevitable.

Magical thinking is a bi-product of cognitive process that were useful in our evolutionary survival. We're so good at seeing patterns that we see patterns everywhere, even when they don't exist.

Truth is a quality of reality. It has nothing to do with what I believe. Truth, when it comes to empirical issues, is an objective thing. Whether something is true or not is independent of whether I think it is true or not, and a lot of people confuse this.

Everybody has regrets- the only people who don't are babies, sociopaths, and people with brain damage. You might wonder why an emotion that's objectively so unpleasant is also so ubiquitous? Well… it's because it's useful (if we treat it right).

You cannot show-off in space, we must be humble. The only purpose for us to seek journeys into space is to learn about the unknown. That's a spiritual conquest. Leaving the solar system has no commercial benefits.

The role of science is to educate us about our reality – and we shouldn't be afraid of it. Once we recognise reality, we can adapt to it. If you don't recognise reality, you act irresponsibly, and your actions won't match the environment.

The only way for you to discover something new is to acknowledge the ocean of ignorance in which you are just an island. Experts have a problem with that – they want to get prizes, and get recognised by their colleagues and peers as being very smart.

Science is a learning experience. We are interacting with nature, collecting evidence, and sometimes nature is more imaginative than we are. We ought to be humble when collective evidence, and not assume we know the answer in advance.

Curiosity drives human progress; it helps us understand our world and that's what drew me to leave my home. I had this curiosity, like Isaac Newton when he saw the apple fall and wondered why.

We can literally see in science that having an open mind, an openness to the unexpected, and the right goals and direction create a greater likelihood of success. This mindset literally gives people the permission to look- and act- on the unexpected.

The lucky person walks down the street, sees the £5 note, picks it up, goes into the coffee shop, and sits next to the businessperson, they have a conversation, exchange cards, and leave thinking they've potentially had a great opportunity. The unlucky person ignores the money, and sits next to the person without making conversation.

The rate of change has become exponential and us as human beings physiologically have not been able to adapt. We just cannot physiologically adapt that quickly – what does it mean for us? This is in some ways Darwinian because he said it wasn't about the strongest that survives, it's those that are most able to adapt.

Gender identity drives self-socialization. People think adults socialise their children, but children socialise themselves. We see the same process in the Great Apes. Self-socialisation we see, is not limited just to humans! That's why I talk about the idea of gender in apes, not just sex.

Primatologist & behavioral psychologist who studies animal cognition and emotions

When you observe chimpanzees and other apes, you see how extremely humanlike they are in almost everything they do. We have been so indoctrinated to think we are special (as a species) that when you see an ape up close and see they are- in essence- us, you don't know what to do with those feelings.

There was a revealing study which showed this too. If you tap out the rhythm to a familiar song, say 'happy birthday…' how often do you think that someone listening to your taps will guess the song? The person tapping usually guesses about 50%, but in reality, it's about 2.5%!
