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.
本文涉及对零假设的接受，即一个变量对另一个变量没有影响。尽管经常有相反的观点，但在某些情况下，这个零假设可能是正确的。接受零假设的适当标准是：（1）零假设是可能的；（2）结果与零假设一致；（3）该实验为发现影响做出了充分努力。这些标准与心理学的元规则一致。充分努力标准是主观的，这有点不理想，但另一种选择——从不接受零假设——既不理想也不实际。
