Abstract
By bringing a test of temptation and self-control preferences to the domain of information acquisition, I collect experimental evidence on whether individuals experience self-control problems relating to information.

Primary Outcomes

Primary Outcomes (end points)
The shares of individuals strictly preferring commitments to avoiding or seeing information rather than choosing in the next session (& comparison across treatment arms). Note that there are three possible measurements of preferences, increasing in conservatism: the first is after the basic survey elicitation, the second after a time cost must be borne, and the final accounting for WTA. Each imposes a harsher requirement for preferences to be considered strict. We will conduct analysis across all measures, noting that measure 2 (post time-cost) is our primary focus.
Primary Outcomes (explanation)
Preference rankings over choice menus are elicited in round 1 of the experiment using standard procedures. We can identify strict preferences for commitment by extracting those who strictly prefer to not be offered information in session 2 relative to choosing next time.

Secondary Outcomes

Secondary Outcomes (end points)
Share of individuals demonstrating dynamic inconsistency in information preferences (& comparison across treatment arms)
Final consumption of information across treatments
Comparison of preferences across qualitative measures of risk attitudes, time preference, impulse control, altruism, and sentiment about bonus choice.
Secondary Outcomes (explanation)
We will examine the share of those who strictly prefer (not) to avoid information in session 1, who then go on to (not) access information in session 2.

Experimental Design

Experimental Design
The experiment occurs over two sessions, conducted online.
In session 1, participants make a choice with a small probability of a negative consequence if a selfish action is taken. Afterwards, they discover that in session 2 they will be offered information on whether the consequence did occur. They are then offered commitment devices to seeing or not seeing the information.
In session 2, depending on commitments made in session 1, information is offered to participants and they choose whether to see it or not.
Experimental Design Details
The experiment occurs over two sessions, conducted online.
In session 1, participants decide whether to take a $4 lump sum payment, increasing their payment for the experiment by almost 200%. They are informed that there is a 'small' chance (in reality, 15%) that $15 will be removed from a donation to an international charity if they take the bonus. Afterwards, they discover that in session 2 they will be offered information on whether money was actually removed from the donation due to their action, framed as "opening an envelope". Opening the envelope is assigned a randomly assigned price, to be paid out of the existing bonus. We then elicit participants' preferences over the information menus they will face in session 2: definitely seeing the information, not being offered the information, or choosing next time. Indifferences are encouraged through follow-up questions.
There are two treatments, "Partial" and "NoInfo". In Partial, participants know they will first see a notification telling them there was either a 0% or a 20% chance that money was removed from the charity donation. The information in the envelope then confirms this was or was not the case, conditional on seeing the 20% notification. In NoInfo, the envelope contains the initial notification. Thus, in NoInfo, more information can be avoided via commitment.
In session 2, depending on commitments made in session 1, information is offered to participants and they choose whether to see it or not.
Randomization Method
Randomisation of treatment groups and prices of information is done in javascript (via Qualtrics) during session 1 itself. Randomisation of implemented preferences, preference payments and information content is done in R using session 1 data.
Randomization Unit
Individual
Was the treatment clustered?
No
