Experimental Design (Public)
|
Before
The experiment is implemented online on Amazon Mechanical Turk via Cloud Research. Before randomization, we collect the socio-demographic characteristics of respondents, as well as their perceived importance and knowledge of the policy issues used as main outcomes. Participants are then randomized into (i) treatment messages, each consisting of written policy recommendation on two policy issues, and (ii) control messages, where the same policy recommendations are reported separately (i.e. from different sources). The issues bundled differ in ideological value, policy domain, and complexity. After reading the messages, respondents are asked to provide their policy preference of the two issues.

Participants are then randomized into (i) treatment messages, each consisting of written policy recommendation on two policy issues, and (ii) control messages, where the same policy recommendations are reported separately (respondents observe one recommendation at a time). The issues bundled differ in ideological value, policy domain, and complexity. Before and after reading the messages, respondents are asked to provide their policy preference for the two issues (in the main experiment, one preference is asked before treatment while the other is asked after treatment).

Sample size (or number of clusters) by treatment arms
|
Before
For each pair of proposals on issues X and Y, an equal number of respondents will be allocated to the following three conditions: (i) X and Y made by the same source (ii) X and Y made by different sources. (iii) no message shown. Subjects will be assigned evenly to conditions.
|
After
For each pair of proposals on issues X and Y, an equal number of respondents will be allocated to the following three conditions: (i) X and Y made by the same source (ii) X and Y sent separately (i.e., not sent together by the same source). (iii) no message shown. Subjects will be assigned evenly to conditions. We plan to assign 600 subjects to each condition.
