@alex3619 do we risk substituting mind / brain dualism for mind/body dualism here!?!
I prefer to ditch mind entirely. Even thought is an aspect of brain. Every time we have advances in science that make more specific claims, especially if proven, then we should adopt the new terms until they are disproved, at least as tentative new terms. Vague and ill defined terms allow vague and irrational claims to be made more easily. Rational claims can be wrong, but at least they do not have the added risk of fallacies. Checking the facts and predictions of rational claims, when objective observations are considered, is part of the scientific enterprise.
Mind/brain dualism is common. I am an its-all-brain monist. If mind exists then one day it will be proven. If not then we will keep waiting for it to be proven till we give up on the idea ... which might be many centuries.
I do not claim we understand how the brain works. We are still early on that path. I am going with the simplest hypothesis, for which vast amounts of objective supporting data are available. I would love to see someone prove the existence of mind, it would lead to a big change in how we do things if we have an established understanding of mind. We just do not have this right now.
Humans are far more neuroplastic than originally thought, and one of the main ways we make and remake connections in our brain is by thinking.
This is both correct and vastly oversold. Do they often cite the vast regions of the brain that are hardwired or limited? There is no learning there. Learning occurred during brain development, then switched off. Aspects of visual detection occur here. There are hardwired corrective mechanisms, so the brain can be changed, but this is about changing the brain, not thoughts.
Changing thinking can lead to improved coping. I think there is adequate evidence for this. How we quantify that is very dubious though.
There are also risks. Take asthma and CBT. Studies were done showing big improvement, mostly by asking patients how they felt. Here is the problem ... this changes their question answering behaviour, a type of conditioning, but not the disease state, at least in asthma. When objective outcome measures were used there was no benefit. Its a similar story with schizophrenia. This area is plagued by bad research methodology.
You can create new behaviours with thinking and acting in new ways. This needs to be proven in the case of improving objective disease states, and is a big problem with diseases we do not understand yet. How do you measure objective improvement there unless with secondary factors like hours worked, physical activity, or dosage of medication needed, etc.?
The psychogenic proponents keep claiming that changes in thought lead to all sorts of changes in brain, yet proof is lacking. I do not doubt there is some limited change. The question is how much, and does it lead to objective improvement? If, for example, CBT were used to improve coping in ME, and excessive claims about efficacy were not made, and it were an optional therapy for patients to try if they wanted help, then I would have no objection to it. I have done CBT myself, back in the early days when it was still about rational thought and not behaviour modification on top of that.
Once we have objective outcome markers for ME, such as PEM markers, then the efficacy of many treatments can be tested. Who knows, maybe CBT of types other than currently used in psychogenic ME research do help! We are just not at that point yet.
