Everything is F*cking Nuanced: The Syllabus

Psych 342: Everything is Fucking Nuanced
Prof. Alison Ledgerwood
Class meetings: Ongoing, forever

A common theme in discussions about replicability and improving research practices across scientific disciplines has been debating whether or not science (or a specific scientific discipline) is “in crisis.” The implicit logic seems to be that we have to first establish that there is a crisis before research practices can begin to improve, or conversely, that research practices need not change if there is not a crisis. This debate can be interesting, but it also risks missing the point. Science is hard, reality is messy, and doing research well requires constantly pushing ourselves and our field to recognize where there is room for improvement in our methods and practices.

We can debate how big the sense of crisis should be till the cows come home. But the fact is, whether you personally prefer to describe the current state of affairs as “science in shambles” or “science working as it should,” we have a unique opportunity right now to improve our methods and practices simply because (a) there is always room for improvement and (b) we are paying far more attention to several key problems than we were in the past (when many of the same issues were raised and then all too often ignored; e.g., Cohen, 1992; Greenwald, 1975; Maxwell, 2004; Rosenthal, 1979).

In this class, we will move beyond splashy headlines like “Why most published research findings are false,” “Everything is fucked,”* and “Psychology is in crisis over whether it’s in crisis” to consider the less attention-grabbing but far more important question of Where do we go from here? Along the way, we will learn that the problems we face are both challenging and nuanced, and that they require careful and nuanced solutions.

Week 11: Keep Reading...

*Note that in contrast to the other two headlines mentioned here,

Sanjay’s Everything is Fucked” title is obviously intentionally hyperbolic for comedic effect. He goes on to write: “What does it mean, in science, for something to be fucked? …In this class we will go a step further and say that something is fucked if it presents hard conceptual challenges to which implementable, real-world solutions for working scientists are either not available or routinely ignored in practice.” His post, as well as the other two articles noted here, raise important issues in thoughtful ways. But if you just focus on the titles, as many people have, you might find yourself sliding into a polarizing argument about how bad things are or aren’t. And this polarizing argument can distract us from the more pressing question of how do we get better, right now, starting today.
