Experimental Design

The goal of this experiment is to study the effect of different text message courses on misinformation sharing and discernment. The figure below diagrams the experimental design. We recruited participants through Facebook ads to complete a five-day text message course, plus a pre- and post-survey, for a mobile airtime payment. Participants who clicked an ad were directed to the pre-survey on Qualtrics, where they were first randomized on whether they would see an accuracy nudge in the pre- and post-survey. Conditional on completing the pre-survey, participants were randomized into one of the text message course interventions and enrolled in the course. Participants in all course interventions, except the No-course baseline, received one text message a day for five days starting on the day they completed the pre-survey. Participants in the No-course baseline received the Combo course after the post-survey to ensure we fulfilled our recruitment promise of a text message course. On the last day of the course, participants received a link to complete the post-survey on Qualtrics. Participants who completed the post-survey were paid KSH 500 (about $4 in U.S. dollars) in mobile airtime. Seven to eleven weeks later, participants who completed the post-survey were randomized on whether they would see a prime in the text message recruiting them to a follow-up survey. Participants who completed the follow-up survey were paid KSH 350 (about $3 in U.S. dollars).

Experimental Design

Experimental Design


The pre- and post-surveys each contained 10 posts:

These posts were created by taking 15 facts/domains, then creating a non-misinfo version and 3 misinfo versions (emotions, reasoning, combo), for a total of 60 posts (plus 2 attention check posts). Participants saw each of the 15 facts at least once.

Whichever 3 facts/domains participants saw in the form of non-misinfo in the pre-survey, they saw in the form of misinfo in the post-survey, so these 3 facts/domains were repeated. Which facts/domains were repeated vary by participant.

For each posts, participants were asked 2 questions:

Data

In this script, we use one datasets.

intermediate_data_wide.csv: all data at the user level. Includes treatment conditions, covariates, and individual-aggregated outcomes. Sample of 8,684 participants who completed the pre- and post-survey.

For more information about how these datasets are generated and a data dictionary, see memo.

Samples

This script primarily uses the sample of 8,684 participants who completed the post-survey.

For analyses involving the outcome referred to as the “Primary Misinfo Sharing Rate,” we drop participants who did not share any non-misinfo posts in the pre-survey, leaving a sample of 7,688 participants who completed the post-survey and intended to share at least 1 non-misinfo post in the pre-survey.

Note: *p<0.10; **p<0.05; ***p<0.01 one-sided tests. Robust standard errors in parentheses. Sample includes the 8,684 participants who completed the post-survey. Covariates are de-meaned and interacted with a treatment condition indicator. The list of 18 demographic covariates includes age, gender, education, marital status, geographic location, employment, religiosity, and social media use (frequency of use; self-reported proportion of posts user typically shares). Misinfo and Non-Misinfo Sharing rates and Accuracy scores are measured at the pre-treatment survey.





t-stats ratio.


Ratio between t-stats: with vs. without controlling for covariates.

Difference between post- and pre-treatment outcomes

The following models take the difference between post- and pre-treatment sharing/accuracy outcomes as the dependent variable.

Post–Pre-treatment difference:

\(y_{it+1}= \beta_1[T_i] + \beta_2{X}_i\times[T_i] + u_{it+1},\)


where \(\textit{y}_{it+1}\) = {\(\textit{Misinfo Sharing Rate}_{it+1} - \textit{Misinfo Sharing Rate}_{it-1}\),

\(\textit{Non-misinfo Sharing Rate}_{it+1} - \textit{Non-misinfo Sharing Rate}_{it-1}\),

\(\textit{Sharing Discernment Score}_{it+1} - \textit{Sharing Discernment Score}_{it-1}\),

\(\textit{Misinfo Accuracy Score}_{it+1} - \textit{Misinfo Accuracy Score}_{it-1}\),

\(\textit{Misinfo binarized Accuracy score}_{it+1} - \textit{Misinfo binarized Accuracy score}_{it-1}\)

\(\textit{Non-Misinfo Accuracy Score}_{it+1} - \textit{Non-Misinfo Accuracy Score}_{it-1}\),

\(\textit{Non-Misinfo binarized Accuracy score}_{it+1} - \textit{Non-Misinfo binarized Accuracy score}_{it-1}\),

\(\textit{Accuracy Discernment Score}_{it+1} - \textit{Accuracy Discernment Score}_{it-1}\)}.


\(T_i\) is a vector of binary indicators for No-course Baseline, Facts Baseline, Emotions, Reasoning, or Combo treatment conditions.

\({X}_i\) is the set of de-meaned demographics.

\(u_{it+1}\) are robust standard errors.


Means by treatment group.

t-stats ratio.


Ratio between t-stats: with vs. without controlling for covariates.

This table shows the ratio of the standard errors of the model controlling for covariates. (numerator) and the standard errors of the model without controlling for covariates. (denominator).

AIPW

Estimate treatment effects using Augmented Inverse Probability Weighting (AIPW) (see Robins et al., 1995) for the set of outcome variables and covariates defined previously. Both the propensity score and outcome predictions are obtained through probability forests (Athey et al., 2019).


All predictions are out-of-sample predictions (cross-fitting is based on 5 folds).


For propensity score estimation with probability forest:

  • 5,000 trees grown in the forest.

For outcome prediction with regression forest:

  • 5,000 trees

  • 400 trees in each “mini forest” used to fit the tuning model

  • 500 forests used to fit the tuning model

  • 2,000 random parameter values considered when using the model to select the optimal parameters.

Post-lasso OLS

\(y_{it+1}= \beta_1\mathbb{I}[T_i] + \beta_2\textit{Pre-sharing}_{it-1} + \beta_3\textit{Pre-sharing}_{it-1}\times\mathbb{I}[T_i] + u_{it+1},\)

Where \(\beta_2\textit{Pre-sharing}_{it-1}\) are the predictors that survived the lasso penalty.

\(\beta_1\) are coefficients calculated without the lasso penalty.


Data are split into 10 folds for cross-validation.

Covariates are de-meaned. Treatment group indicators are included in the Lasso estimation and not penalized.
