Answer:
- Falsifiability.
Step-by-step explanation:
'Falsifiability' is defined as a theory, hypothesis or proposition that could be shown or displayed to be false. It is the ability of a statement or proposition to be proven as false. It assists to distinguish between scientific and non-scientific theories.
In the given situation, the concept of 'falsifiability' is demonstrated here as the later research proves the previous hypothesis as false as it discovers an exception of 'heightened hearing..highly correlated with overall intelligence' to the previous proposition 'intelligence was strongly related to one’s sensory capacity'. Thus, this situation illustrates the critical thinking concept of 'falsifiability'.
