A more pragmatic approach is to estimate the potential impact that stress can have on the outcome of an outage. To enable this, I’m in‐ troducing the concept of “stress surface,” which measures the percep‐ tion of the four relative stressors during an outage: the novelty of the situation, its unpredictability, lack of control, and social evaluative threat. These four stressors are selected because they are present dur‐ ing most outages, are known to cause a stress response by the body, and therefore have the potential to impact performance.
