What we need to do is assess psychological theories by seeing what predictions they make, whether that is that listening to Mozart makes you smarter, that you learn better when information is presented in your preferred learning style or whatever it is, all of these are testable empirical predictions, and the only way we can make progress is to test these predictions against the data in tightly controlled experimental studies.
我们需要做的是， 通过心理学所做的预测 来评估这些心理学理论， 无论是听莫扎特音乐能让你更聪明， 或当信息以你较喜欢的学习模式 呈现出来，你会学得更好， 无论它是什么，所有这些 都是可检验的以经验为依据的预测， 我们唯一能取得进展的方式就是 在严格的对照实验研究中 用数据去检验这些预测。
