A more revealing name for 'true?' and 'false?' would be 'boolean-which-equals-true?' and 'boolean-which-equals-false?'. Since the 'identity' function isn't a boolean both functions return 'false', and '(= false false)' is 'true'.
'(true? (true? identity) (false? identity))' would return, you guessed it, 'true'. A more revealing name for the _implementation_ you assumed 'true?' and 'false?' had would be 'truthy?' and 'falsey?'
