KK: /dɪsˌkɒnfərˈmeɪʃən/
The act of providing evidence that proves a belief or idea is false or less acceptable.
The scientist presented disconfirmation of the previous theory with new data.
Disconfirmation → It is formed from "dis-" (meaning apart or away) and "confirmation" (from Latin "confirmare", meaning to strengthen or make firm). The word "disconfirmation" refers to the act of negating or rejecting a confirmation, essentially taking away the strength of a previously established belief or assertion.
Think of 'dis-' meaning to take away and 'confirmation' meaning to make something firm. This helps you remember that disconfirmation means to take away the firmness of a belief or assertion.
