Global workspace theory is a description of how our minds work. The word global refers to the whole mind or brain, not the world.
The central feature of this theory—the global workspace—is conscious working memory, or working memory that could be made conscious with minimal effort.
This global workspace is also what a great deal of Buddhist mindfulness attends to. If we focus our attention on what is coming in and out of our global workspace, we will gain many insights into how our minds operate.
The Buddha’s five skandha explanation of consciousness can be understood as a form (or percepta) entering the global workspace.
Consciousness is the fifth skandha in the chain of skandhas. It is very important to recognize that whatever we become conscious of is not necessarily right.
With this in mind, we can see that being mindful of what is entering and leaving our global workspace can help us forestall errors from forming and growing in our minds.
In the Buddhist tradition, ignorance (a kind of error) is the deep source of all delusion.
But how do I know if the percepta or bits of information entering my awareness are right or wrong?
Well, there is science and Bayesian thought processes to help us, and they are both very good, but is there anything else?
What about my actual mind? My psychology? My understanding of my being in the world? How do I become mindful and more right about these?
Besides science and Bayes, I can ask an honest friend who knows me well if the percepta I think I just received from them is right or wrong.
If my friend knows the game, they will be ready to answer me before my global workspace changes too much. If my friend confirms my interpretation of what they just did or said, I will know that my interpretation (or consciousness) is correct.
If they disconfirm, I will know that my interpretation was incorrect, a mistake.
This kind of information is wonderful!
We calibrate fine instruments to be sure we are getting accurate readings from them. Why not our own minds?
This kind of calibration can be done in a general way, but you will get a general answer in that case. If you want a precise reading, a mindfulness answer, you need to play the FIML communication game.
