That’s not how science works. I understand that you’re trying to criticize the field, but lack of predictions, even reliable ones, is not itself a problem it has. For one thing, even false theories can make reliable predictions, like Levoisier’s defunct theory of caloric in the 18th century which has now been replaced by modern thermodynamics. The caloric theory can be used to make mathematically accurate predictions, but the underlying theory is still wrong.
Similarly, evo psych can make a lot of reliable predictions without saying anything true. On the contrary, one criticism of the field is that it’s unfalsifiable because an evolutionary theory can always (allegedly) be proposed to fit the data. Which is to say, you’re barking up the wrong tree.
One example: it is proposed that the fusiform face area of the brain is a domain specific module evolved for face detection. It’s present in other animals that recognize conspecifics by their face. In humans, damage to the area leads to face specific agnosia. The theory makes accurate predictions, but is it true? It’s still being debated.
Without predictions and without tangible models you don’t have falsifiability. You unintentionally acknowledged my point without understanding it. The field isn’t a science, just philosophy trying to explain the results from actual sciences, but didn’t itself have any kind of proof of validity.
Your example is much more closely related to neurology and neuropsychology.
From the fact that language of our complexity would be very hard to learn if humans didn’t have specialised circuits for learning it, and the fact that evolving better language on a biological level would improve fitness.
Okay, here’s another. Large pupils are a sign of health and of arousal, and make humans feel more attraction, because it’s a better mate for breeding. Ads that leverage a model’s attractiveness will perform better if they use models with bigger pupils or digitally enlarge them.
Hypothesis for an existing observation without any robust underlying model. Even the advertisement bit is just a weak correlation which was observed after the fact and not predicted in advance based on any model
Making predictions and conducting manipulation experiments isn’t possible / practical in all fields of science. Medicine, astronomy, archaeology, evolution and climate studies are other examples.
Yes. It is unethical to give someone a disease so you can study it. Best we have are case studies of people who got the disease and are being treated for it.
In climate studies, it is not practical to increase temperature or humidity by x% and see the effects. Again, you have case studies - either from the past or from parts of the world that are warming much faster than the rest. Or you can do mesocosm experiments where you warm, say, a square metre of grassland, and see the effects. But then there is a lot of uncertainity in scaling up the findings of such small-scale studies.
Astronomy at least collects a lot of data from those one-time observations and try to model the physics, hoping to be able to see something similar again to calibrate the models. For medicine it varies, for rare disease and injuries that are unethical to replicate its a valid issue but they still have scientific models of the affected organs, etc, and similarly to above they try to model it and predict what treatments would work. And all your examples have historical data to some extent.
Evopsych have essentially zero usable historical data and adds no new understanding over regular psychology, and I’ve never heard anybody talk about how they expect behaviors to actually have formed over generations (nor does it meaningfully cover learned and taught behavior)
Show me a prediction it makes

If you raise a group of human children without ever exposing them to language, they’ll invent their own.
That’s a prediction
Derived from what? From observation of the exact same thing already happening, or from a model of behavior?
From the fact that language of our complexity would be very hard to learn if humans didn’t have specialised circuits for learning it, and the fact that evolving better language on a biological level would improve fitness.
That’s untested, even if it appears likely, it’s a hypothesis which doesn’t predict how it would be formed or learned or how it would be used, etc

It is impossible to make prediction or cobduct manipulation experiment in medicine and in climate studies? Do you read what you post?
Yes. It is unethical to give someone a disease so you can study it. Best we have are case studies of people who got the disease and are being treated for it.

You don’t need to give anyone a disease to study medicine. Moreover, medicine is not limited to diseases. And it has both predictions and experimets.
You still can observe, describe, analyze and model(predict). The goal of every science is to create prediction function.
Astronomy at least collects a lot of data from those one-time observations and try to model the physics, hoping to be able to see something similar again to calibrate the models.

Astronomy is mostly history sprinkled with physics.
