Anecdotal Fallacy

Exceptions should not be used to dismiss sound arguments. Yes, the chain smokers lived till 98, Yes, the alcoholics
reached full life expectancy, Yes, the guy didn’t study and got straight A’s, Yes, toxic work culture gave huge profits for the company, Yes, eating high-fat foods didn’t give the heart attack, Yes, all these things did happen.
There’s no doubt about that but they do not in any way nullify the general rules and principles. Believing contrarily is the perfect example of anecdotal fallacy.
By the way, high-school drop-outs have become billionaires but it doesn’t mean you drop out of it now.
