rationality and irrationality, like sanity and insanity, can be measured in this way:
all human behavior is directed by the perception of self-interest - you do what you
think will be good for you
true self-interest is that which will
actually benefit the individual
the distance, or difference between the perceived self-interest and actual self-interest is a measure of rationality
this sounds odd, right? for obviously, when a fireman rushes into a burning house to save a stranger, this would seem to be a clear instance of the
disregard for self-interest - selflessness
this is a fallacy: the fireman's self-interest is determined individually -
is he the type of person who could stand by and watch another person die while able to help?
if not, then self-interest (the ego) demands an action which, from another perspective, may seem selfless - or foolish
however, the fireman is merely being consistent with his self-image - for him, not to act would force him to reevaluate his entire view of himself -
negatively -
in short, for him, the danger involved in acting is less frightening than the thought of being a coward
which makes running into a burning building the more rational, the more sane, choice
humans
seem to behave in self-destructive ways, to be sure...
but truly, they are, all of them, servicing their own perceptions of interest
and perception is all about perspective
the guy with diabetes and high-blood pressure keeps eating at McDonald's because 1) the food tastes good, (at least to him) 2) it is familiar, and
therefore comforting, 3) it is inexpensive, 4) the perceived difficulties in maintaining a healthy diet, along with the anxiety that goes along with
sudden change, ultimately discourage the subject from making (or even seeing) the choices that would result in improved health 5) the future is
uncertain (a rationalization)
for this subject, the (perception of) fear of disease or even death is too remote to alter behavior that (he believes) has benefitted him in the past
(the devil you know is better than the devil you don't)
society itself has a profound impact on perception - the foods you eat, clothing you wear and thoughts you think have been shaped by society
(whichever society) since infancy
it is unlikely that our diabetic would have eaten himself into disease if peers and family had not created the perception of quality for McDonald's
by taking him there as a child
whatever ideas pass for normal in any given society will affect individual perceptions
the japanese soldiers in WWII, famed for their suicidal charges, seem to be irrational, until you consider things from their perspective -
that death before (familial, cultural) dishonor was ingrained into their psyches, their egos, their perceptions of self... in order to make the
irrational rational
and on it goes
the more worrisome point here, is that currently, much of a person's world view (in which the ego is anchored) is constantly manipulated by
individuals in a position of advantage, who would stand to gain from irrational behaviors
the funny part is, that these PTB that take advantage of fellow humans are, in fact, very often acting against their true self-interests - since
whatever gains are made are frequently corrupted by the net-negative impacts of the manipulation -
think about how BP might have benefitted from this understanding - they saved a million that cost them billions
summing up, (most) humans aren't self-destructive... it just seems that way because you are sane
be patient with them... they are but young and may yet prove their potential
