G8 Guru

About G8 Guru

Expertise is real, it is valuable, and it is far narrower than the people selling it want you to believe. Learning to judge it is a skill in itself.

This magazine is called G8 Guru, and the name is a small joke at its own expense. A guru, in the way the word travels now, is someone whose authority is general: they know, and you do not, and the boundary of their knowing is never drawn. That figure is the thing we are sceptical of. Expertise, by contrast, is one of the most valuable things human beings produce. Somebody who has spent fifteen years doing one difficult thing, getting it wrong, being corrected, and doing it again, holds knowledge you cannot reason your way to from your armchair. The problem is not that experts exist. The problem is that expertise and the appearance of expertise look almost identical from the outside, and only one of them is common.

So the question this publication keeps returning to is practical rather than philosophical. Not whether anyone can be trusted, because plainly they can and you already depend on it every day. The question is how to tell, in a specific case, whether the person in front of you knows what they claim to know. That is a skill. It can be improved. It is not the same as being generally suspicious, which is cheap and useless and mostly makes people worse at deciding things. A blanket refusal to believe anybody is not scepticism, it is just a different way of not thinking.

Competence is local, and the evidence that it does not transfer is everywhere once you look.

Understanding a subject means discovering its complications, and complications make people hedge.

Whenever a claim touches something you know, treat it as a free calibration sample.
