Right, but only sometimes.That does not mean that what you said applies in my case above. just that you think so. "Very subject to" is not hard facts, it is hand-wavy. Very poor logic on your part, because I clearly said, above:

>Sheer sense of taste and common sense is enough.

Those are good enough ways of judging situations in some cases, particularly day-to-day life issues, i.e. applying heuristics, common sense, empirical reasoning, etc. Works for me and many others, for many, even most, non-hard-science cases. E.g.: See what others said in this thread about tomatoes. Do you do a mathematical proof for every such judgement call (like which tomato to buy, organic or industrial), that you make in life? if so, you must have a huge backlog, ha ha, or not have time to have a life at all.
