Wisdom in fragments

You can think of the human mind as a measuring instrument. We're making judgements all the time and studies show that on a day-to-day basis, when presented with the same evidence, our judgements may be different. If you see the mind as a measuring instrument, you start to see it as a scale, a bafflingly variable and noisy scale.

Each person is trapped in their own world and assume that the rest of humanity sees the world the same way that they do. That assumption is incorrect. You see the world differently to me, and that's true for every situation in which we find ourselves. It's a side-effect of how we're built!

The easiest way to understand noise is by thinking about measurements. Suppose you are measuring a line with a very fine ruler. You will expect some variability such that you will not get the same number every time when you measure. That variability is noise. In the mathematics of accuracy, the expression for total error is very simple and quite compelling. It is bias-squared plus noise-squared. Bias and noise are both contributing to error and in that equation, they do so on the same basis.

Even if we could live to 1000 years, life would still be too short for many of us. I'm 51, that went in a blink of an eye. I don't think finding purpose in our lives will be an issue.... Longer life gives us a more purposeful life.

I used to be skeptical about whether I could live an additional 5 years. Now, I'm convinced that I could live 20 years beyond what I would have done. Drugs on our near horizon will give us easily another 20 years, and the drugs not far behind that, another 100. I've never been more excited about the prospect of human health than I am right now.

We are literally right now living through one of the biggest revolutions in human history, certainly in medicine, and most people aren't even aware that it's about to happen. Economically, the world is going to be much richer if people live longer. That means more money to spend on urgent challenges such as climate change.

Ageing is not separate from Alzheimer's or heart disease. The leading causes of those diseases is the ageing process, which we can now control. Based on what we're doing in the lab, we know that if you turn the clock back, those diseases go away- that's a revolution. We've been working on a band aid system trying to fix the diseases that are already there, while ignoring the main cause.

In my lab, we can control ageing easily. We have mice where we can dial up the ageing process or reverse it. It's not that hard when you know how. Until recently, we didn't know there was a backup copy of the information which has been corrupted, and now we can reset it using an embryonic gene trick. Ultimately, I think we'll be able to pop a pill and reset our body's age.

Ageing is malleable, we can control it. 20% of our health in old-age is due to genetic factors, and the rest is due to our lifestyle. We can measure this clock. It's literally measuring chemicals in our own DNA. Here's the good news…. That number can be changed. If you smoke, if you don't exercise, if you eat lots of fatty foods, that number will accelerate and if you do the right things, perhaps even take some medicines, you can slow that number down – even reverse it.

You have to step back and focus on the merits of the offer- not the person who brought the offer to you. That's how you defend yourself. You recognise that there's something that goes on first as important as the message itself inclining you towards purchase or agreement.

I'd been a patsy all my life, an easy mark for the appeals of fundraisers or sales operators who would come to my door. I'd end up with unwanted magazine subscriptions… There must be something other than the features of the offer that got me to say yes, because I don't want those features, it must be the way the offer was presented to me.

The people who influence the best are the ones who take the advice of the ancient Chinese military expert, Sun Tzu. Every battle is won before it's fought. If you put people in a mindset that is congruent with the major focus of the message you are yet to send them, it opens the door to persuasion.

We have the tendency to follow those who are comparable to us. It reduces uncertainty and provides us with an extremely effective shortcut into deciding how to best behave in a world that has become overloaded with information and stimulus. We need shortcuts!

If you go into a new situation where you don't know anybody and you want to be more influential, don't look around the room and say hmmm… who can most help me here?… instead, look around and say hmmm…. Who can I most help here? You will put that person in a position where they will be standing on the balls of their feet to help you!

I'm drawn here quite often to thinking about impressionist art like Monet or Pissarro which have a beautiful incompleteness- they're just scratches and blobs on canvas but done so well that the brain is drawn into completing the image. That's partly why paintings like that have such aesthetic appeal- because they're engaging the mechanisms of the brain in completing the picture.

Neuroscientist & leading researcher on consciousness and perception

Emotions are perception, but perception of the body itself. You see something scary like a bear, that triggers all kinds of physiological changes in your body. Your heart rate increases, your breath quickens, and the perception of those changes is the emotion. Emotion is another kind of controlled hallucination but geared to the interior of the body rather than the outside world.
