“in terms of their own realities and their own situation.” is a huge caveat. Essentially plenty of customers behave irrationally – by any sensible definition of rational. I agree, to make them customers and keep them as customers you need to develop theories that can make sense of their behavior. And it doesn’t make sense to think if they behave irrationally that means randomly (chaotically, unpredictably, uncontrollably). Customers can be predictably irrational (as a group).
Seeing that people will chose* to fly lousy airlines because the initial price quoted is a little bit cheaper than an alternative (or because they are in a frequent flyer program) you can say the customer is behaving rationally if you want. Coming up with some convoluted way to make their decision, which based based solely on their desired outcomes (and cost factors etc.) is not rational, to be seen as rational seems like a bad idea to me. Instead figure out the models for how they fail to behave rationally.
They consistently chose an option they shouldn’t rationally want; in order to save some amount of money they don’t care about nearly as much as the pain they will experience. And the amount they will then complain about having to suffer because they chose to deal with the badly run airline. That isn’t rational. It is a common choice though.
The problem is not in thinking the customers are being irrational for not buying what you are selling. The problem is in thinking the customers will behave rationally. Your theory should not expect rational behavior.
There are plenty of other examples where customers make irrational decisions. I don’t think calling them rational (within the irrationality of their “own realities” makes sense). People will buy things because they think it is a better bargain to get the more expensive item that is the same, for more money, because originally the store charged more and now it is on sale. Anchoring isn’t an understanding of how people are rational. It is an understanding of how psychology influences people in ways that are not rational.
People are driven by brains that, while capable of being rational, are quite often not rational even within their own realities (in any way that seems sensible to consider that phrase – in my opinion). If people don’t understand basic math and make bad choices about what options are cheaper that doesn’t mean that they make the right choices within their own reality (of failing to apply 8th grade math correctly to the situation); it means many people can’t do basic math in the situations they encounter in their lives.
I suppose you can call it being rational to do make the choices people make (“within their realities” – which I guess means in this context non-rational realities). Or you can call it being foolish. Or you can call it basic psychology that can be used by marketers to manipulate people.
I don’t suppose the word you use matters as long as you accurately understand what you customers will actually base their purchase decisions and happiness on. However, I think it is better to acknowledge people are just often irrational than to try to explain that things are rational from their non-rational reality.
Another example of irrational but predictable behavior. Those that are less knowledgable do a worse job estimating their knowledge (they overestimate what they know so think they are better able to make good decisions than they are). This is known as the Dunning-Krueger effect. You can train people to overcome this tendency to bias rational understanding in favor of what we would like to believe. This bias is especially bad if we are very unskilled in an area and not used to getting feedback on our weaknesses. Effective self reflection on where you are failing to be as good as you can be helps correct this bias and allows you to make better rational decisions.

The Drucker Institute went on to quote much more sensible things Drucker said, in my opinion
I think this idea is right. The problem is in trying to equate understanding the customers motivation and decision making to a rational process. Customers are manipulated all the time and it is rarely because they are shown new evidence that rationally educates them to make a better decision (though it is possible to education customers). It is normally by manipulating the psychology of people into making irrational decisions for the customer that happen to help those doing the selling.

* Granted, in the airline example, some time people don’t even have the option (either there is no decently run airline to chose or they work for a company that doesn’t respect people and doesn’t give any weight to the suffering they impose on their employees).
