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theories can make reliable predictions, like Levoisier’s defunct theory of caloric in the 18th century which has now been replaced by modern thermodynamics.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.
