Suppose Wendy and Rachel have different opinions about my average response time M in the online game.

Wendy's prior for M (shown as the red curve) is normal with mean 240ms and standard deviation 30 ms, and Rachel's prior (shown as blue) is normal with mean 260 ms and the same standard deviation.

The black vertical lines divide the possible values of M into "fast", "average", and "slow" regions.
