The latter is evidence you know what you are doing. And evidence of above average intelligence. Stupid people think they know entire breadths of knowledge - call Peter Principle or Dunning–Kruger: overconfidence is more dangerous to yourself and everyone around you than knowing your limits.

You can NEVER know everything so a heavy awareness of your limits and gaps is critical to being the best you can be. It means you have the _potential_ of operating around the edge of your limits. Realizing your limits (as they exist in the moment) is essential to pushing those limits.

People suffering from Dunning–Kruger have no clue how far over or under those limits they are operating.

This is also related to why you must have grades from A to F in school - you can't know where your knowledge boundary is without breaking it and sometimes failing. You aren't really trying or you are operating in dangerous ignorance.

Another analogy is you can't know the strength of a material without breaking it or reaching its strength limit.

Absolutely this, the more you know the more you realise you don't know. I think the best kind of knowledge is T-shaped - a niche, narrow pillar of a subject you know inside out, and a broad and shallow range of technologies you are at least on Christmas-card terms with, if not competent.

Also, most things correspond to patterns and the more experiences you have (and/or the older you get), the more enriched your mental models become, and the more areas you can apply those patterns to. E.g. there are a thousand syntactic variations of IF-THEN-ELSE but once you know the pattern, you can apply it to anything.

Years of learning the above are why I now leave all decisions to PHBs. They say they know nothing, but are then willing to decide everything. So I just do what they say. Products take longer to deliver and are less what the customer wanted and have zero innovation, BUT the PHBs seem to have the influence to keep the gravy line open longer than me.

(I can’t decide whether to tag this satire or not)

> Stupid people think they know entire breadths of knowledge - call Peter Principle or Dunning–Kruger:

Just to add: Dunning-Kruger is not a problem of "stupid people". We're all susceptible to it, and we all fall victim to it from time to time in different areas. If anything, people with self-perceived "high intelligence", or people that are genuine experts in one field, can sometimes be the most susceptible because they overestimate how much their knowledge transfers.
