When I started my undergrad I was quite interested in various fields related to cognitive science, but in my country there was no way to major in that. I started a psychology major, and while I did get to take courses related to cogsci, and work part time in more neuroscience-y research, I also had to take several courses in clinical psychology and not one, but two! courses on psychoanalysis. They were taught by profs that were very much into Lacan. My conclusion after all this coursework (and several books outside the syllabus) is that while these ideas are sometimes interesting from a literary and, let's say, continental philosophy angle, they're of dubious clinical value and totally bunk from a scientific point of view. I had to stop myself from laughing sometimes when it came to the pseudo-mathematical formulations because they really are nonsense (for a good summary on that aspect, see Sokal's "Intellectual Impostures"). This wasn't the only reason, but I ended up switching majors to CS to focus on AI/ML (a good decision in retrospect!). Years later, I still think of Freudian and Lacanian ideas sometimes, though - they do have a certain appeal.
