I don't even know if you can be honest with your self and call psychology a science.  I guess it's as close to science as a person can get given the number variables involved in human thought.

Yeah but understanding human motives and behaviors is certainly a valuable thing...

I guess it's safe to say that science has its limits?

It's valuable for sure, I like it.  Yeah science has it's limitations.

40% can be replicated.

Pretty good article. Some highlights:

Quote:

"The results are more or less consistent with what we've seen in other fields," said Ivan Oransky, one of the founders of the blog Retraction Watch, which tracks scientific retractions.




AKA it's not just psychology

Quote:

the results might be a little too generous; in reality, the replication failure rate might be even higher.

"I say this because the 100 assessed studies were all published in the best journals, so one would expect the quality of the research and the false rates to be higher if studies from all journals were assessed," he said.




AKA the cream of the crop were selected to try and replicate. there may be far worse results in lesser known journals.




I also really liked the example replication study. I think it really highlighted how replication is never really replication. Lots of things change. I once compared a scientific study to an optical illusion. When very specific elements are in place, you get to see this. But how can you possibly replicate the very specific elements? Especially with something as shifting as culture? Or language? Or any number of dynamic factors. It gets pretty slippery pretty quick. At best it is a temporary finding and most people understand that IMO.

IMO a better test than replicability, for psychology findings, is a variety of validity measures. Construct validity, concurrent validity, convergent validity, and discriminative validity to be more specific. If one can take findings, create a hypothesis from the findings, test the hypothesis, and get results in line, then this is a good indication that the original findings were not baseless. In fact they informed a related concept effectively. Which as far as I know is the "point" of reporting scientific findings in the literature. To inform future studies. Not to be stone tablets as many try to make them.

p.s. I know that the method section of the paper is included for replicability purposes. I think that over the years this can be seen as a misnomer of the scientific method. it is good to include for the purpose of thinking through one's method, as well as guiding future research, but I do not think it serves a great function for replication. I think replication, with some notable exceptions, may be a misguided ideal of research. I do however think replication has a sound reason to be in practical matters e.g., engineering.

Maybe.  Psychology is very, very hard.  Perhaps the hardest science there is.  That is sure to keep psychologists employed because it takes a lot of work to develop a working theory.

How come so many people smoke cigs and drink soda if psychological manipulation doesn't work?

At least those two particularly employ an addictive agent, what I can't seem to fathom is how in god's name they got people to watch all this shitty reality programming and listen to Justin Bieber!
Such powers I cannot ignore. :bow:

Sure, but not until you try them. And more than once.

Only 100 were replicated in this study and from this study only 40 could be replicated. The numbers are really bad and cannot speak for all subfields within psychology, statistics or whether or not psychology is a "real" science. Truly, generalizing from 100 replicated studies is simply nonsensical.
