decision making
Your internal criteria decide what is signal and noise.
Signal detection theory posits that your response criterion depends on your current decision threshold.
Your response criterion (not sensitivity) is what shifts based on what you value. Sensitivity (d') is generally considered a fixed measure of an observer's ability to discriminate between signal and noise.
What you notice depends entirely on what you fear missing.
Where this comes from
- Study
- Green & Swets, 1966, Signal Detection Theory
- What the check found
- SDT correctly posits that decision thresholds shift based on value (payoffs), but standard theory holds sensitivity (d') to be a distinct, stable measure of perceptual ability independent of those biases.
- Confidence
- Solid, with limits
