And yet both people are able to function in such a way as to successfully reproduce on a wide spread scale. Clearly, whatever it is that religion includes it must include a working model for reality that is capable of being reproduced in humans.
Interesting criteria for determining "functionality." Though any system necessarily engenders itself. Otherwise that system would no longer exist anymore.
Whether or not that mental model leads to greater or lesser agreement with extant reality... Well, I will play Devil's Advocate for a moment: I am a sollipsist. Prove to me that you exist.
Will you accept Cogito Ergo Sum? Lol.
In terms of what my personal opinion on the matter: I do tend to agree that most religions contain less truth value than other competing world views. But the core of the argument is essentially correct: Isolate the variable "Theism" and look at the reproductive success of the competing world views. Non-theist world views reproduce just as successfully (some might argue that in modern times that the direction is swinging; that theism had its time where it was more successful; I'll leave that argument to sociologists) as theist world views. This means that theism as a variable contributes nothing to how viable your mental model is.
Out of curiosity, what do you precisely mean by "reproductive success?"
1. Mere success rates at reproduction. A Boolean measure.
2. Average number of children by religious vs non-religious couples.
3. Total number of children conceived by religiouos vs non-religious couples.
4. "Quality" of children children conceived by religious vs non-religious couples.
5. Etc.
Why is this standard necessarily better than say "truth value" or say another standard of comparison like say "benefit to humanity"?
Fair enough. I don't have any problem with science based on the scientific method.The only issue with psychology is that from what I've seen it's at the point in it's development that mathematics was when they invented the number zero. In other words, they know very little about the subjects they're studying
Sometimes even science based on the scientific method is absurd.
xkcd: Significant
Unfortunately a result of the terrible system of advancement in academia and the terrible system in which journal articles are selected for publication.
Also, I feel its somewhat unfair to compare psychology as a whole to math (for one thing, I wouldn't call math a science, a point which is debatable). People are much much much more complicated than numbers. And some branches of psychology are rather quantifiable and specific, it really depends on what you're specifically looking into. I.e. Clinical psychology, which is the branch you likely refer to when they bring psychologists to testify whether a person is insane or not, is often very subjective. Psychologists who study language or memory, or neuroscience, or the senses, just to name a few are all typically quite rigorous.
