Understanding Understanding

Functional Accounts of Emotions are Useful. Here's an Example of Why.

“The greatest enemy of knowledge is not ignorance; it is the illusion of knowledge.” – Steven Hawking

Many researchers in the field of psychology don’t appear to understand that restating a finding is not the same as explaining that finding. For instance, if you found that men are more likely to gamble than women, a typical form of “explanation” of this finding would be to say that men have more of a “risk bias” than women, resulting in them gambling more. Clearly this explanation doesn’t add anything that stating the finding didn’t; all it manages to do is add a label to the finding. Now some psychologists might understand this shortcoming and take the next step: they might say something along the lines of men perceive gambling to be more fun or more likely to payoff than women do. While that might well be true, it still falls short of an complete explanation. Instead, it would merely push the explanation stage back a step to a question about why men might perceive gambling differently than women do. If the researchers understand this further shortcoming and take the next step, they’ll reference some cause of that feeling. If we’re lucky, that cause will be non-circular and amount to more than the phrase “culture did it”.

The smart money is on betting against that outcome, though…

The distinction I would like to draw is between understanding per se and the feeling of understanding. The examples given on wikipedia reflect understanding per se: the ability to draw connections among mental representations. Understanding per se, then, represents the application of knowledge. If a rat has learned to press a bar for food, for instance, we would say that the rat understands something about the connection between bar pressing and receiving food, in that the former seems to cause the latter. The degree of understanding per se can vary in terms of accuracy and completeness. To continue on with the rat example, a rat can understand that pressing the bar generally leads to it receiving food without understanding the mechanisms through which the process works. Similarly, a person might understand that taking an allergy pill will result in their allergy symptoms being reduced, but their understanding of how that process works might be substantially less detailed or accurate than the understanding of the researchers responsible for developing the pill.

Understanding per se is to be distinguished from the feeling of understanding. While understanding per se refers to the actual connections among your mental representations, the feeling of understanding refers to your mental representations about the state of those other mental representations. The feeling of understanding, then, is a bit of a metacognitive sensation; your thinking about your thinking. Much like understanding per se, the feeling of understanding comes in varying degrees: one can feel as if they don’t understand something at all through feeling as if they understand it completely, and anything in between. With this distinction made, we can begin to start considering some profitable questions: what is the connection between understanding per se and the feeling of understanding? What behaviors are encouraged by the feeling of understanding? What functional outcome(s) are those behaviors aimed at achieving? Given these functional outcomes, what predictions can we draw about how people experiencing various degrees of feeling as if they understand something will react to certain contexts?

Maybe even what Will Smith meant when he wrote “Parents Just Don’t Understand“

This brings us to the second question: what behaviors are motivated by the feeling of understanding. If you’re a particularly astute reader, you’ll have noticed that the term “understanding” appeared several times in the first paragraph. In each instance, it referred to researchers feeling that their understanding per se was incomplete. What did this feeling motivate researchers to do? Continue to attempt and build their understanding per se. In the cases where researchers lack the feeling that their understanding per se was incomplete, they seem to do one thing: stop. That is to say that reaching a feeling of understanding appears to act as a stopping rule for learning. That people stop investing in learning when they feel they understand is likely what Hawkins was hinting at in his quote. The feeling of understanding is the enemy of knowledge because it motivates you to stop acquiring the stuff. It might even motivate you to begin to share that information with others, opting to speak on a topic, rather than defer to who you perceive to be an expert, but I won’t deal with that point here.

Given that people often do not ever seem to reach complete understanding per se, why should we ever expect people to stop trying to improve? Part of that reason is that there’s a tradeoff between investing time in one aspect of your life versus investing it in any other. Time spent learning more about one skill is not time not spent doing other potentially-useful things. Further still, were you to plot a learning curve, charting how much new knowledge is gained per-unit of time invested in learning, you’d likely see diminishing returns over time. Let’s say you were trying to learn how to play a song on some musical instrument. The first hour you spend practicing will result in you gaining more information than, say, the thirtieth hour. At some point in your practicing, you’ll reach a point where the value-added by each additional hour simply isn’t worth the investment anymore. It is at this point, when some cognitive balance shifts away from investing time on learning one task to doing other things, that we should predict people to reach a strong feeling of understanding. Just as hunger wanes with each additional bite of food, feelings of understanding should grow with each additional piece of information.

Also like hunger, some people tend a touch more towards the gluttonous side.
