The document proposes using biofeedback methods to facilitate knowledge transfer by quantifying tacit knowledge. It hypothesizes that 1) tacit knowledge is partially externalizable by observing reactions, 2) mental and affective processes are coupled in the brain and subtle physiological changes reflect learning, and 3) personal discovery occurs through social comparison. The approach involves biomonitoring participants during tasks to build a database of physiological "fingerprints" of behavior across demographics. Data synthesis would integrate signals into models to extract representative parameters of tacit knowledge.
