Always ask to see the evidence.
A lot of what we read in textbooks and newspapers is wrong.
Asking a basic question like why? or how? three times in a row can take one to the frontier of knowledge. When we realize that not knowing opens the door to wisdom, we can actually expand the limits of what is known.
Don't take anybody's word for it; check the primary sources and archives yourself. I collected more than 14,000 archival photographs and newspaper articles for my most recent book. I’ve collected a few of them for you to investigate under “Evidence.”
