IDENTICAL products Kyser. If you offered me the latest Tom Robbins book for 10 quid and then someone else offers the identical book for 8. then being a rational person I would by the latter.
And 999 people out of 1000 would do the same. Just because there is an occasional madman who decides not to, does not mean that it doesn't hold logically...
But no one said that people
don't act rationally did they? Now, this seems to be the difficult bit for you to get so I'll say is slowly.
People can sometimes be rational.
Sometimes they aren't.
The rational actor model assumes that people are rational
all the time.
This is a falllacy because it is clearly not true.
People behave irrationally all the time.
See, Rand assumes, as the model does, that humans are perfectly rational. Even if someone is rational 99.999% of the time, that 0.0001% time they aren't fucks the model, and people behave irrationally far, far more often than that.
For example - I earn £1,000 pcm. I have to pay £500 in rent&bills, I wish to buy a Prada handbag that costs £600. This will leave me no money for transport, food or disposable income, however I go ahead and buy it, leaving me in debt and unable to feed myself for a month.
That is an irrational decision, but is an example based in fact from a woman I once worked with - she basically got into debt and virtually starved herself for a month in order to buy a handbag.
That is irrational behaviour.
