True, but have you noticed that the so-called "experts" in the the US just ignore our personal experiences? They brush us off as "anecdotes".
And individually we are. However, when Dr F assembled that flavor survey with?1000s (I remember it being very high, more than 1000s, but don't want to put down some super high number and be wrong) of respondents assembled in an accepted manner regarded as valid by the FDA we stopped being anecdotes and became demonstrable evidence of the importance of flavorings to our success at stopping smoking.
@BillW50 remember skepticism is what drives science. It's the "prove it to me" approach. And when properly employed it works. Look at Einstein's theory of General Relativity. It continues to be tested to this day, and in every test has properly predicted the observation. Can't argue between that, the photoelectric effect, conversion of mass to energy that the guy was pretty smart. Yet he believed to his last day that quantum physics was incorrect. He worked years on a grand unifying theory to get quantum physics tossed. Yet quantum theory has stood up to repeated experimental testing and held together and advanced quite well, while the grand unified theory never went anywhere. So you can still be really smart and still be wrong. And that's OK, science works best when you learn from the mistakes and negative data too.
Oh and it wasn't experience that told you putting water in a cup of ice made it cold. It was you sticking your finger in to test if it was cold. After that consistently worked you didn't have to do it anymore because it was reproducible.
