Controllable stupidity is one of the components of my theory of gravitation (see page About a Theory).
Each person has certain amount of stupid things to do in his/her life. So, if we do some of them intentionally, or under control, it will reduce a number of uncontrollable stupidities, with overall stupidity balance unchanged.
And if this idea is stupid, I made safe stupid assumption without hurting anybody and reduced my overall allocated stupidity by one point.
If this idea is not true, at least it is entertaining, I hope.
There are some advices how to implement controllable stupid things, e.g. http://www.simoron.ru/ for Russian speaking audience.
