Experimental Design (Public)
|
Before
Each experimental session include a series of decision tasks. In each task, we use a choice list to elicit a subject's matching probability for a bet on one state. We incentivize subjects using the random incentive system: At the end of the experiment, (only) one line in the choice list among all decision tasks will be randomly selected for payment.
We also include comprehension checks in our experiment to make sure that participants read and understand the instruction. The participants who fail the comprehension quiz will be excluded and not be able to take part in the decision tasks.

Secondary Outcomes (End Points)
|
Before
We will examine how often a subject updates away from a signal, i.e., how often a subject (1) reports a matching probability lower than 50% when (the color assigned to) Option A is the same as the hint (i.e., state = signal), and (2) reports a matching probability higher than 51% when Option A is different from the hint.

We will also examine if the reported matching probability is lower when Option A and the hint are the same than when Option A and the hint are different.

Secondary Outcomes (Explanation)
|
Before
Such reverse belief updating behavior can be an indicator of whether a subject has a good understanding of the experimental environment. In the main analysis, we will focus on the subsample that excludes the subjects who exhibit reverse belief updating for more than 1/4 of tasks.
