+Signal Detection Theory (SDT) is a framework for understanding how we make decisions when faced with uncertain stimuli, distinguishing a true signal from mere [[Noise](/wiki/noise)]. It quantifies the ability to perceive faint information and the influence of individual [[Bias](/wiki/bias)] on detection performance. This theory finds application across fields, from [[Perception](/wiki/perception)] to medical diagnostics.
