Ok, so now let's use this new-found wisdom we have about our D-K blind spot. How do we ensure that we don't both fall into a D-K blind spot scenario and we don't ever act (make decisions)?
Also - I tend toward the more negative end of the spectrum, i.e. I don't have the confidence, but I'm probably smarter than 90% of the population. Aaaand - as a Brit - Just saying that is making me cringe with embarrassment.
Smarter than 90% of the population would be an IQ of 120 (s.d. 15) which is pretty high. You can test yourself here: http://www.iqtest.dk/ . Let us know if you got your 120. :)
Is the D-K "wisdom" useful?
