Planned Number of Observations

Before
Around 800 "splitters", and around 160 "audiences", for a total of around 960 subjects. Each audience member is matched with 5 splitters. A little bit more than 960 subjects might be recruited to account for inattentive responses.

After
Around 800 "splitters", and around 160 "audiences", for a total of around 960 subjects. Each audience member is matched with 5 splitters. A little bit more than 960 subjects might be recruited to account for inattentive responses.
Update: due to a large number of low-quality (inattentive or rushed) answers, especially in the two "public" treatment arms, an extra 600 splitters are recruited (along with an extra 120 audiences), so as to obtain around 200 high-quality responses per treatment. This put the total number of subjects to around 1680.
