- It’s okay if participants see the logic underlying a self-report questionnaire, e.g., can guess what the subscales are. It’s a self-report questionnaire — how else are they going to complete the thing? (Related: lie scales — too good to be true?)
- Brain geography is not sufficient to make psychology a science.
- Going beyond proportion of variance “explained” probably is necessary for psychology to become a science.
- People learn stuff. It’s worth explicitly thinking about this, especially for complex activities like reasoning and remembering. How much of psychology is the study of culture? (Not necessarily a criticism.)
- Fancy data analysis is nice but don’t forget to look at descriptives.
- We can’t completely know another’s mind, not even with qualitative methods.
- Observation presupposes theory (and unarticulated prejudice is the worst kind of theory).
- Most metrics in psychology are arbitrary, e.g., what are the units of PHQ-9?
- Latent variables don’t necessarily represent unitary psychological constructs. (Related: “general intelligence” isn’t itself an explanation for anything; it’s a statistical re-representation of correlations.)
- Averages are useful but the rest of the distribution is important too.
“Most of his students were young apprentices in the building trade, and when he walked in to teach his first class he asked them what it was they wanted to learn – what difficulties did they face in their lives that he could really help them with? It turned out that their greatest concern was with lack of sleep. So Colin duly crammed his brain full of the scholarly literature on sleep and set about teaching a term of classes on the art of sleeping. It is a story that has always stayed with me as a teacher, the ultimate example of making an effort to meet your students’ needs.” Roman Krznaric on Colin Ward
“At the most fundamental level, education happens between individuals — a personal connection, however long or short, between mentor and student. Whether it’s personally answering a question raised in class, spending twenty minutes working through a tricky idea in office hours, or spending years of close collaboration in a PhD mentorship relationship, the human connection matters to both sides. It resonates at levels far deeper than the mere conveyance of information — it teaches us how to be social together and sets role models of what it is to perform in a field, to think rigorously, to be professional, and to be intellectually mature.”
