There are many thousands of considerate, generous people who want to develop a career in caring for people, alleviating suffering, providing some form of treatment. Many enter the medical professions studying to be doctors, nurses, physiotherapists, radiologists, and a host of other specialties.
If you look at the courses on offer, though, you will see not only the medical and scientific ones, but also some that provide qualifications in Complementary and Alternative Medicine, CAM for short. These often stress words like holistic, energy-based, non-invasive, and integrative, and claim to provide forms of medical care not addressed by conventional medicine. The institutions offering such qualifications now include many mainstream universities.
One would think, since mainstream universities are validating these courses, that there is some serious established basis for their contents, that they were determined to be factual and meet a high intellectual standard, that the skills imparted are genuine, evidence-based, and reliable. That's what you would expect if you went to university to study say, engineering, or chemistry, or architecture. Your qualification from a university would indicate that you had met certain demanding academic and professional standards, and that the courses you had studied were rigorously assessed as to the factual basis of their content. Unfortunately, we can no longer assume that is the case.
As the CAM movement sought mainstream acceptance, it generated its own institutions, produced its own teaching materials, issued its own qualifications, published its own journals, produced its own trainers and lecturers, and largely side-stepped the usual arbiters of academic and professional competence. Alongside the traditional academic institutions – the universities – there arose many different colleges offering qualifications in everything from crystal healing to Ayurvedic medicine, from homeopathy to light therapy, from reiki to magnets, and they operate with very different standards.
Some universities in the UK have, until recently, been issuing Bachelor of Science degrees in homeopathy alongside degrees in physics and biochemistry. Although there are strict scientific criteria for the inclusion of subjects into university academic curricula, the CAM courses slipped through the net. Those homeopathy B.Sc. courses have now been closed down – it's difficult to award a science degree based on a non-science for which there is absolutely no evidence. Nevertheless, there remain many pseudoscience courses mixed in with genuine science courses. Some universities are rebranding these pseudoscience courses as arts degrees, to avoid scientific scrutiny, and are issuing B.A. degrees instead.
