Resilience presents a challenge for psychologists. Whether you can be said to have it or not largely depends not on any particular psychological test but on the way your life unfolds.

The cognitive skills that underpin resilience, then, seem like they can indeed be learned over time, creating resilience where there was none.

The truth is that we have no idea what the long-term effects of any artificial enhancement may be. Will our brains be able to withstand running at artificially heightened capacity?

We don't appreciate luck in life when things are going well. No matter how smart I am and how I prepare, there are things that catch you off guard.

Perhaps one day we'll be able to identify and block not just scams but the scammers themselves - before they even target their first victim.

Poker isn't the roulette wheel of pure chance, nor is it the chess of mathematical elegance and perfect information. Apart from the underlying mathematics, poker depends on the nuanced reading of human intention, interactions, and deceptions.

That's the power of the good con artist: the ability to identify your deepest need and exploit it. It's not about honesty or greed; we are all suckers for belief.

Understanding the psychology of changing norms starts from a simple insight: although we may wish to be perfectly rational and impartial, bias is an inescapable part of what it means to be human.

Stories bring us together. We can talk about them and bond over them. They are shared knowledge, shared legend, and shared history; often, they shape our shared future.

Bullying is the result of an unequal power dynamic - the strong attacking the weak.

I'd studied acting in New York when I left Pierre - that was the big thing that I did. I worked very hard at it, actually.

My life has been extreme. Most people will not have the experience I've had. But the things that changed me, really changed me, they happen to everyone.

Every life is extraordinary.

Oh, am I a feminist? I usually say that I was an accidental feminist. Really, I was just being me.

I think I devoted my life to Pierre Trudeau and our beautiful children.

There was imbalance with my first husband just by the given of our 29-year age difference and the difficulty of me being this unformed, enthusiastic young woman and he already completely in place being the leader of the country.

Depression is 80 per cent of my condition, and 10 per cent is mania, and 10 per cent is what we call normal. I say that must be when I am buying groceries. Or vacuuming.

The problem with mental illness, as opposed to physical illness, is that it involves wrong thinking or impaired insight. You're not thinking correctly.

I have a lot of lovely things in my life that I wasn't able to have before I got healed from my imbalanced life.

Being bipolar is a huge exaggeration of your emotions. You can be pretty high and also terribly low, so I've been through it all.
