Another thing that is missing is for the field to adopt decision theory properly. At the moment it's usually left to the patient to decide that a treatment is not working for them and pick a different therapist. If we can't predict which treatment will work, we should at least have some research into how long to try each one, and in what order, and any indicators that might allow us to switch early from one that is not working. At the moment I think a huge amount of suffering is endured because therapists don't have good incentives to give up when their treatment isn't working. (At least in my country in the private sector. The public sector has different issues - they are incentivised to declare victory early - and I don't know how it works in the US)
