Maximizing improbability means spouting gibberish 24/7 and flopping around uncontrollably. Very unpredictable.

More seriously, I don't see how "improbable" is what you should maximize. If you come from a certain background, ending up in prison as a murderer may be more improbable than countless good lives you could lead.

No, that’s just falling into the “lol so randum xD” meme.
