Watch evidence accumulate in real-time
Subjective Value: The internal "worth" you personally assign to the silver. This varies based on your financial goals, sentiment, or need.
Market Price: The actual dollar amount required to buy the silver right now.
The Drift Rate (v) is the gap between value and price: v = Subjective Value - Price. A high positive drift means the purchase is a "no-brainer."
Caution Threshold (a): How much evidence you need before deciding. High caution reduces noise-induced mistakes but slows you down.
Information Noise (s): Randomness in neural processing or market signals. High noise can lead to irrational choices.
Observe how the signal evolves in real-time. Use the Simulation Speed slider to move through trials more quickly. Explain to students that Noise causes the jaggy path, while Drift dictates the general direction. The Caution Threshold acts as a filter: the further apart the boundaries, the more 'noise' is filtered out, but the longer the process takes.
