wouldn't you psychoanalyze yourself to death?
Well, survival instincts would probably kick in before then, but I suppose I could just as much analyze myself to death as I could talk, walk, sleep, play videogames, or focus on any one activity to the point where I collapsed from lack of something.
Since I would imagine such analysis would be heavily mathematical and boring, watching TV to death seems more likely.
Furthermore, psychiatrists can already analyze behaviors to a good extent, however they are still kicking around, and I doubt they analyze themselves as much (if at all) as their paying customers.
How could you function knowing how your actions are pre-determined?
Now this is entirely different, just because you know how something works, does not mean you can predict it. For example, a computer program is written by a person, and it is run on a machine that is fully understood. However, the complexity of it means that, short of running it, given a large set of conditions, the outcome could not be easily predicted. Example: if given the source code for a video game, and a set of buttons the user presses at what time, you would have immense difficulty determining what the screen would look like (down to the pixel) at a given time.
Of course, such examples are possible to figure out, since you can always run the program. A better one would be a coin: consider that we understand gravity (on earth concerning a coin at least), fluid physics (for the air currents), momentum, etc... All of the properties of our coin, but to predict, with 100% accuracy, the side it will land on is impossible.
So even when we understand how are brain works, doesn’t mean we can determine what a given brain will do. There are over a billion neurons that need to be accounted for, and an exponentially grater number of molecules. Taking chaos theory into account, unless it was a small brain over a short period of time, the actions would be completely different, since even a small error in weather a molecule will react a certain way can throw off entire decisions down the line.
Finally, simply because you know how something works, or how to solve a problem, does not mean you must. I know perfectly well how to find the first 50000000 prime numbers, without using mechanical aid, and attempting to do so without eating would kill me, if I don’t die of boredom first, but there is no way in hell I would undertake such an Endeavour.
