Obviously, I can only go on anecdotal evidence. Yes, Lewis really took the piss with the published work, and I cared enough, I might even read through the actual paper. But as Can't think of anything witty... said, Psychology is not an easy subject, and it's no more a soft science than Computer Science is the same as IT. Accounting for differences I've seen between the US and the UK, psychology tends to pad the early courses with the Freud and Skinner, because they are often used as classes for general education credits and it's easier than trying to learn about action potentials, anatomy, and neurochemicals.
My experience is that most psychology professors laugh, outwardly even, at the crap produced in the early to mid 20th century that is passed off as psychobabble in media today. It's only those who want to major in psychology that get introduced to the neuroscience, psychophysiology, chemistry, and the like. Once you are there, the first thing you learn is statistics... real statistics. And not just how to use Minitab, but the logic and rules behind the theory of statistics. You also learn the same research methods found in medicine and science, like lab procedures, ethics, etc. It's all there. And it's not easy.
And personally, I work in IT, or would if my current company hadn't worked hard to keep business and system analyst hybrids on the business payroll (I'm sure it makes the accounting easier). My math and analytical background from psychology has opened more doors than if I had signed up to learn programming languages in college (in retrospect, it would have opened more doors to have at least learned some along with my degree, even if I didn't want to go through those doors right away). Not to mention the stigma in interviews is not nearly as bad as what IT folks experience (I'm assumed to have people skills... ha!)
I also love the bitter grapes that people have over "working hard" in college, while assuming others did not. I knew CS majors and math majors who were just as likely to sleep through class, get drunk every night, and still stumble to the finish line and get a degree. Psychology had them as well, and if my brother's description of his engineering university is anything to go by, they probably lost more engineers to drowning in their own vomit than academics. It's what college students do, and some can handle it, others cannot. To belittle an entire field of study because you don't understand it is rather ballsy, especially when there is nothing other than your own bias and superiority complex to back it up.
