It is because the methods pyschs and sociologists use are largely ineffective and the people who do it know that the literature is not reliable. The anxiety/etc experienced by these people results from realizing they don't know wtf they are doing. There are people with problems who can be helped somehow, but no good, practical algorithm for figuring out how is available. The field needs to focus resources on assessing effectiveness properly and stop throwing a million sociologists with notebooks at the problem. The brain is just a really, really complex machine we don't have the schematics or source code for. If something is worth doing it is worth doing right and I have come to realize over the last year (I am a neuropharm grad student) much of biomed, psychology, and sociology is not being done right. These people need to start figuring out the power of math and real stats.
I agree, most psychologists and sociologists don't know what they're doing. Much of the problem is that psychology and sociology is treated in the classroom as an isolated discipline. If you try to bring up mathematics and try to use it to support a therapeutic model, good luck. Believe me, I've tried. Nobody wants to hear, for example, how the mathematical proof of 'the boundary of a boundary = 0' has implications for therapy. Moreover, in research and statistics classes where mathematics do come into play, people over-emphasize the importance of mathematics to the point where they ignore the limitations of statistical analysis. Correlation is often mistaken for causation, validity for soundness, and everyone thinks that just because something is published that it must be correct.
Case in point of the stupidity that I was taught, I had a social policy professor claim that "the cause of oppression and injustice in society is the result of bad social policies," to which she added, "which means that the only way to remove oppression and injustice is to create good social policies."
I raised my hand in class and said "bullshit." Assuming her premise is true (which it's not), then it would be axiomatic that you need to remove ALL 'bad' social policies and start over from scratch.
I firmly believe that the things I am talking about in this thread are going to become more prominent in the future. I am making a bold statement when I say this, and I know it can come off as very arrogant. But believe me, I've put in an incredible amount of time formulating these ideas. I acknowledge that most of them are not new. But, they didn't come from the predominant psychological and sociological models. They come from biology, math, quantum mechanics, philosophy and logic, physics, chemistry, etc. in addition to psychology and sociology. To this extent, the ideas presented here are comprehensive in scope, and there's a ton of information to support my claims that I haven't yet posted.
I've become a complete convert to the bayesian way of thinking. I believe once there is a critical mass of researchers thinking in that manner it will go a long way towards improving the system. Second point is that researchers need to reduce their reliance on government funding in every way possible. The very basis of the funding is arguably unethical, on top of that it relies on a relatively easily corruptible, centralized authority that distributes funds for reasons other than merit. Science is very, very sick right now and I know I am not alone in this opinion. I don't have time now but once I have finished my current project I plan to spend some time developing a system to crowdsource funding of individual components of research proposals (to supplement government funding..for now) and crowdsource some of the tedious work when possible. I would encourage others to attempt the same in their free time.
