Suppose you meet someone who is poor. How do you tell whether they have "business savvy", and how do you avoid your judgement of that being affected by the fact that you know they're poor?
It's all just anecdotal evidence. You can't just point at someone and I could to tell you how savvy they are.
I just note the people I know who come out ahead or behind in their dealings, just as I note when someone says something fairly profound, finds a rather ingenious solution or writes a bit of clever code to guesstimate intelligence.
I wasn't representing it as anything other than a working theory from personal data. But it's not like Adams started from a statistical argument either.
I figured my experiences and generalizations were a fair response to his.
