I call sentences like 'this is true', 'that is false', 'that makes sense' "vulgar metaphysics". Many Programmer like to use it all the time. It is very often a good sign you get conformation bias. I prefer people who say 'I wrote a test and the values does not match. After some time I could pin it down to that function. After fixing it I wrote some more test to cover the cornercases.' Many programmers love to use metaphysics and logic in a quite fundamentalistic way. I my experience this is not very productive. ;-)
