Self-Normalization Delays Recognition of Overload
Context
Study of developer self-assessment accuracy during gradual workload increases compared with objective performance metrics.
Observation
Developers consistently underestimated their cognitive load levels as workload gradually increased. Self-reported stress levels showed an average 45% deviation from objective stress indicators during sustained high-load periods.
Insight
Gradual increases in cognitive load appear to trigger adaptive self-normalization, making it harder for individuals to accurately assess their own stress levels over time.
Why This Matters
Reliance on self-reporting may significantly underestimate actual cognitive load. This suggests the need for objective monitoring systems independent of self-assessment.
Limitation
Research conducted in relatively stable project environments. Dynamic or crisis situations may show different self-normalization patterns.
