So I did what you suggested and plotted the number of top level posts and total posts over time. The attached graph is averaged over the last 20 open threads. Code available here: https://gist.github.com/TRManderson/6849ab558d18906ede40
I don't trust myself to do any analysis, so I delegate that task to you lot.
EDIT: Changed GitHub repo to a gist
That's not quite the law of the excluded middle. In your first example, leaving isn't the negation of buying the car but is just another possibility. Tertium non datur would be He will either buy the car or he will not buy the car. It applies outside formal systems, but the possibilities outside a formal system are rarely negations of one another. If I'm wrong, can someone tell me?
Still, planting the "seed of destruction" definitely seems like a good idea, although I'd think caution in specifying only one event where that would happen. This idea is basically ensuring beliefs are falsifiable.
Thanks. Just going to clarify my thoughts below.
Because doing so will lead to worse outcomes on average.
In specific instances, avoiding the negative outcome might be beneficial, but only for that instance. If you're constantly settling for less-than-optimal outcomes because they're less risky, it'll average out to less-than-optimal utility.
The terminology "non-linear valuation" seemed to me to imply some exponential valuation, or logarithmic or something; I think "subjective valuation" or "subjective utility" might be better here.
The blue line suddenly stops because the last comment is posted at that time. I was kind of lazy about this graph and did have labels and a legend, but apparently I was too out of it to realise they didn't show on the png.
As said by gwillen, x axis is minutes.
