Model (1) includes original tweets only; Model (2) includes original plus retweeted tweets
Table shows results from OLS regressions of the time variable tweetday on the 25 binary topic variables along with the 25 topic variables interacted with indiv, a binary variable with values of “1” indicating tweets sent by humans rather than bots. The coefficients on the 25 interaction terms are our coefficients of interest and thus, for ease of presentation, all non-interacted terms have been omitted from the table
