Law of the instrument
‘The law of the instrument, law of the hammer,[1] Maslow’s hammer (or gavel), or golden hammer[a] is a cognitive bias that involves an over-reliance on a familiar tool. As Abraham Maslow said in 1966, “I suppose it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.”’ From https://en.wikipedia.org/wiki/Law_of_the_instrument
