First off, we're dealing with social constructs. Your social construct of what height is may be very different than the construct that the people you're talking to have. These constructs are also tied to each other. This is a really crucial reason why that list model we just looked at doesn't work, because the list the items on each list are not independent of each other. There's other information that link these things to each other. This means that they can strengthen each other and their place in the system, making it harder to dislodge just one of the ideas.

Prescription and description are intermingled in ideology. So, the norm, meaning what most people do or average, and norm, meaning what you're supposed to do, the line between those things pretty much doesn't exist. There's an incredible flow between prescription and description. What does everybody do, and what is it appropriate to do, what is okay to do?

And lastly, individuals have stakes in their own beliefs. These belief systems, we're not all on a search for truth and I hate to tell you this, but even those of us who are researchers are not all on a search for truth. We're doing other things with our days. We have goals. We have social goals as we move through the world, and it turns out that our social goals very much shape the things we believe in, as much right as we don't like to admit that sometimes. How does this play out, for example, with height?
