We have a bit of a global problem right now: confident assertion without evidence (or even despite evidence to the contrary) is valued higher than qualified uncertainty. We must rise above this in the web community. The first step is admitting what we don’t know, then figuring that out before proceeding.
This excerpt has got to do with a current discussion about a new heading element,

I love what Jake says, and I don’t think it is “right now” that we have this problem. I feel it’s very common  for people to assert without evidence, rather than say “I don’t know”. I remember working with one of the first accessibility experts I met, and I remember vividly his telling me that being an expert is being able to say “I don’t know” when you don’t know, as it gives more weight to what you assert when you know what you’re talking about. I’ve tried ever since to apply this approach to my work and life so far.
So, out of context, here’s Jake’s thought as a maxim that could sit on the same shelf as the ability to say you don’t know: Confident assertion without evidence (or even despite evidence to the contrary) is valued higher than qualified uncertainty. Food for thought.
