本文涉及接受一个变量对另一个变量没有影响的原假设。尽管经常有相反的意见，但这种零假设在某些情况下可能是正确的。接受原假设的适当标准是 (1) 原假设是可能的； (2) 结果与原假设一致； (3) 该实验是为了找到效果而付出的努力。这些标准与心理学的元规则一致。尽力标准是主观的，这有些不可取，但替代方案——从不接受原假设——既不理想也不实用。
This article concerns acceptance of the null hypothesis that one variable has no effect on another. Despite frequent opinions to the contrary, this null hypothesis can be correct in some situations. Appropriate criteria for accepting the null hypothesis are (1) that the null hypothesis is possible; (2) that the results are consistent with the null hypothesis; and (3) that the experiment was a good effort to find an effect. These criteria are consistent with the meta-rules for psychology. The good-effort criterion is subjective, which is somewhat undesirable, but the alternative-never accepting the null hypothesis-is neither desirable nor practical.
