ABSTRACT

Does Twitter trigger negative tones in politicians' digital communication? On social media direct feedback mechanisms such as retweets or likes signal to politicians which message and tone are popular. Current research suggests that negative language increases the number of retweets a single tweet receives, indicating preferences for negativity in the audience on Twitter. However, it remains unclear whether politicians adapt to the logic of Twitter or simply follow the rules determined by the broader political context, namely the state of their electoral race. We use sentiment analysis to measure the tone used by 342 candidates in 97,909 tweets in their Twitter campaign in the 2018 midterm elections for the US House of Representatives and map the ideological composition of each politician's Twitter network. We show that the feedback candidates receive creates an incentive to use negativity. The size and direction of the tonal incentive is connected to the ideological composition of the candidate's follower network. Unexpectedly, the platform-specific incentive does not affect the tone used by candidates in their Twitter campaigns. Instead we find that the tone is mainly related to characteristics of the electoral race. We show that our findings are not dependent on our sentiment measurement by validating our results using hand coding and machine learning.

Notes

1 A more detailed discussion of the method and our robustness checks including hand-coding and supervised machine learning can be found in the results section and the appendix.

2 We find the same effects for likes as another possible form of reacting on a tweet. Results can be seen in the appendix Table in the third model.

3 Other measurements of model fit like AIC and BIC also suggest that the model with varying slopes performs better.

4 Descriptive statistics of the coefficient β1j can be seen in Table .

5 Given the small effects of all coefficients, we ran simulations to see how well our model (Equation3) can predict the negativity incentive of individual candidates. We find that our model can predict the true distribution of the negative incentive in our sample, however, it tends to predict higher coefficients than the real values. For more details see Figure in the appendix.

6 Using a subsample analysis of only challengers supports the claim that challengers with a higher win probability can be associated with a more positive average tone in Twitter campaigning. For further details see Table in the appendix.

7 Regression tables using both categorical measurements can be found in the appendix.
