Campbell’s Law .
When a measure becomes a target, it ceases to be a good measure .
Occam’s Razor Law .
So if you saw a woman running towards a bus, you could hypothesise that she has seen the ghost of her dead husband, whom she poisoned, and she’s running as fast as she can away from him, which just so happens to be towards the bus. Or you could hypothesise that she’s trying to get to the bus before it drives away. The former requires a lot of assumptions (ghosts exist; the women was married; she’s a murderer; ghosts are vengeful…) whereas the latter does not. According to Occam’s razor, running to catch the bus is a better explanation..
