We are bad at valuing other people, and we are worse the more different they are than us.

Because of the tax on being different, individual actors in the labour market from different backgrounds can rationally value the same opportunities differently.

The tax on being different is largely implicit. People need not act maliciously for it to be levied. In fact, at its heart is a laudable sentiment: 'prove it to me.' The problem is that we are requiring different levels of proof without realising it.

Discrimination is not done by villains. It's done by us.

The traditional markers people use for hiring can be wrong - profoundly wrong.

I want to literally make people smarter by jamming things in their brains.
