We tend to classify everything promptly as ‘like,’ ‘don’t like.’ Peculiar habit this one for it limits us tremendously. We consort with the ‘like,’ inebriating us with its shallow compliment; and repudiate the ‘don’t,’ rejecting its challenge, missing the boat that for once might have taken us to undiscovered shores.
In our times, I’d call it the Facebook fallacy. Facebook makes us believe that everything must either be liked or not liked (or rather ignored). This is an informal fallacy, an error in reasoning that does not originate in improper logical form. Arguments committing informal fallacies may be formally valid, yet fallacious.
The real name for my Facebook fallacy is the false dichotomy, but it is also known as the false dilemma, black-and/or-white thinking, the either-or fallacy, the fallacy of false choice, the fallacy of exhaustive hypotheses, the fallacy of the false alternative or the fallacy of the excluded middle. It is an informal fallacy in which we only consider limited alternatives when there is at least one additional option.
The options we consider, or give as a choice to our opponent, may be two extremes or completely different alternatives. We can also have a false trilemma (if we reduce the options to three, instead of two).
A false dilemma can be constructed intentionally when we attempt to force a choice. The fallacy can also happen by accidental omission of alternatives or by ignorance. In situations where we are emotionally involved, it is not rare that we only see two (or a few) options to solve a problem when there are several.
As it is, life is not black and white, neither are your options in the vast majority of the situations when you feel cornered.
Life is a rainbow!
