As a psychedelic researcher, I find myself increasingly frustrated by the tendency of the field to make lofty claims about the drugs that stray from the realities and limitations of the data.
For example, psychedelic research that uses neuroimaging employs measures of brain function that are, in fact, quite crude. Typically, one signal in a brain scan can mean many things (amygdala activation can occur when one is scared, happy, observing something salient, etc.).
For this reason, cognitive neuroscientists typically constrain mental activity using behavioral tasks in order to make more educated inferences regarding what is happening in the mind. Yet for some reason, psychedelic scientists believe they can infer mental function from the activity of a few tripping brains under task-free conditions. That is, participants are essentially doing whatever they want in the scanner, making the number of possible inferences one could make nearly infinite. And worse, they base their claims on outdated Freudian theory.
