I’m an academic psychologist at a UK university. As a discipline I think psychology is often misunderstood; students take the A level and/or the degree with little valid knowledge of what it entails. But, part of the problem is that too many think they know what it involves so don’t do their research - they’ve seen Tv shows and think it’s all catching serials killers and analysing people (and their dreams). Then they find it’s not and become disillusioned. I think other subjects that aren’t often studied until A level (economics springs to mind as an example) aren’t as misrepresented in the mass media so people go into them with a more open mind and/or do a bit more research.
Even within this thread I’ve seen a rather narrow and sometimes misrepresented view. Most people here have talked about becoming a psychologist, mainly in terms of clinical psychology. But there are many other types of chartered psychologists (forensic, occupational, educational, counselling, health, sports). These do require further training and the vast majority of psychology graduates don’t go on to become chartered psychologists, but that isn’t particularly different to plenty of other degrees (e.g law). Our graduates do go on to lots of inter-related careers though, that don’t specifically have psychologist in their title but for which their degree has laid the groundwork. So in that sense it’s not a wasted degree - a psychology degree isn’t only worth it to become a chartered psychologist. I’m just thinking about our recent graduates and where they’ve gone - civil service, data analysis, social work, charities/not-for-profit sector, education from primary through to HE, NHS non-clinical roles, NHS mental health practitioner roles, sports coaching, police officers or civilian staff roles, HR, project management, a plethora of graduate training schemes...and lots more! An interest in psychology tends to mean our students are interested in people, understanding how they think and behave, and possibly helping in some way. So they often look for roles that suit this interest and maybe they’re often not the highest paid. So if salary is what you mean by prospects then maybe psychology doesn’t lead to the same prospects as, say, economics. But, our graduates are very employable - they have worked with spreadsheets and numbers, delivered presentations, been taught to think compassionately, written reports, encouraged to think critically etc!
I have also heard that the graduate statistics aren’t always kind to psychology graduates - partly for what I’ve just mentioned but also because it’s collected at a point when a reasonable proportion of psychology graduates (who do want to take the chartered psychologist route) are still doing the junior/adjacent roles to help them get onto their postgrad training courses. So, you end up sampling the salary of assistant psychologist or care home assistant as if that’s their final destination, but give that person another year and they’re on a DClin with a trainee salary of nearly £40k that is only going to rise from there.
