On the Physical Effects Fallacy
This post was prompted by something I read over at Absolutely No DooDahs. As I’ve said before, most of the commentary on Bill’s blog is highly intelligent. So, I feel bad about singling out this most unintelligent (and most unrepresentative) post. However, this myth has been around for several centuries, and has enjoyed the support of some otherwise intelligent individuals; so, it is in desperate need of dispelling.
Regarding Anheuser-Busch (BUD) and Coca-Cola (KO), Bill wrote:
Colored, flavored corn – syrup water doesn’t generate brand loyalty, and neither does fermented hops and barley malt. The desired effects of either can be gotten with off-brand products and substitutes.
This statement is false. The desired effects can not be gotten with substitutes. The demand for a product is not determined by the physical effects of that product on the user.
Most misinterpretations of economic activity begin with a failure to properly define economics as the study of human choice. If the field is further limited in scope, it can no longer explain commerce. In other words, a unified theory of economics must explain all human actions, because humans do not have one “program” for making economic choices and another “program” for making non – economic choices.
The demand for a product is derived from that product’s (expected) ultimate impact. I’m using the word “impact” simply because I want to conjure up the image of the mind as something that is being stamped or imprinted. In ancient times, the idea of the physical world “stamping” the mind was popular, and I think it’s an apt metaphor in this case.
Humans act to effect changes in their mental states; humans do not act to effect changes in their physical state. Human actions that appear to be motivated by a desire to alter one’s physical state are actually motivated by a desire to alter one’s mental state. That’s where the “ultimate” half of “ultimate impact” comes from. Alterations to one’s physical state are merely desirable insofar as they lead to alterations in one’s mental state.
Let me use a few examples. You don’t eat to prevent starvation; you eat to eradicate the sensation of hunger. You don’t take your hand off a hot stove to prevent further burning of your flesh; you take your hand off a hot stove to prevent further pain.
I’m not just splitting hairs here.
Humans are rational in the sense that they act to maximize pleasurable mental sensations and minimize painful mental sensations. They are not rational in some greater sense. For instance, humans have no inherent desire to live, they merely tend to believe living is the more pleasurable state. Some humans weigh all the pleasure and all the pain and find they’d prefer a quick exit. Many rational people have committed suicide under extreme circumstances. The fact that under normal circumstances most rational people do not contemplate suicide doesn’t necessarily mean we are hard – wired to live, it could simply …
