Now, another example of a test of truth, so to speak, that works in the sciences that would probably work in other fields to some extent is that if something is true, really so, if you continue observations and improve the effectiveness of the observations, the effects stand out more obviously. Not less obviously. That is, if there is something really there, and you can’t see good because the glass is foggy, and you polish the glass and look clearer, then it’s more obvious that it’s there, not less.
