But consensus is slow, because it requires agreement, whereas authority is fast, because it works by command. Hence we have a better outcome found slowly, or a worse one found quickly.
Unfortunately, the human mind values immediacy, and thus the human mind has a greater preference for a bad answer given quickly than a good answer given slowly. We also value simplicity (aka low cognitive load for understanding), thus we prefer a short simple bad answer given immediately to a long complex good answer given slowly.
That doesn’t mean these preferences are good, it just means most people have them, and thus we have to consider the predilection for fast-bad to slow-good when thinking about how to get the best outcomes.
