Question

BlackTom AI · Accepted Answer

To tackle the question, let's list the provided options clearly and then evaluate each one in turn.
Option 1: 'keeping the hypothesis that is the most logical and discarding the rest.' This suggests that scientific choice is based on perceived logical appeal rather than empirical evidence. In science, a hypothesis is evaluated by testable predictions and observations, not merely by subjective logic, so this option misrepresents the criteria used.
Option 2: 'selecting two or three of the most popular hypotheses, and voting on which is most appropriate for the times.' Science does not determine truth by popularity or popular vote; consensus can form, but the actual criterion is falsifiability and empirical support, not popularity polls. Therefore this option is incorrect.
Option 3: 'discarding those hypotheses that make false predictions.' This aligns with the core scientific method: hypotheses that fail to predict outcomes or that produce predictions contradicted by data are falsified and discarded or revised. This accurately reflects how competing hypotheses are evaluated.
Option 4: 'proving which hypothesis is true.' In science, proving a hypothesis true in an absolute sense is rare; many hypotheses are provisional and continually tested. Scientists aim to test and potentially falsify hypotheses rather than claim absolute proof, so this option is misleading.
Overall, the reasoning centers on empirical testing and falsification as the mechanism to compare competing hypotheses, rather than logic alone, popularity, or absolute proof.
