A naturally occurring truly pathological example, this would be something like manic bipolar disorder where somebody is in the manic phase or somebody who has taken methamphetamine or cocaine, what tends to happen is that they have lots and lots of ideas, all of those ideas seem really exciting to them. But if you were to talk to them for any given moment, they would be very fixated on one particular tunnel of ideas. And by being fixated on one particular tunnel of ideas like the idea that they're going to run for president tomorrow, this is unfortunately typical of people who have bipolar, which is not to say that everybody who runs for president is bipolar rather people who are bipolar often have these delusions of grandeur that they're somehow going to be president simply because they decided to and that they were selected to do this, et cetera, et cetera. Ideas about themselves and other people that are very constrained. In other words, not very divergent.
