You don't need to have an "expert psych" initially.
Sitting with a friend rehashing what we studied about skinnerian conditioning and a diablo like game we thought of a frankenstinian game which knew exactly when to hit you for a transaction to let you level up/get new item and so on. Years later and micro transaction enabled mobile games came out.
Adding simple psych based analysis to systems isn't hard, you would just pick it up from gaming/other industries and recreate it as a best practice.
People are interested in this, and are doing great amounts of research to figure out how to do it better.
