Methodology

Our dataset includes all original tweets and replies from @elonmusk as of July 12, 2018. It excludes retweets before March 2015 and any deleted tweets.

We read every tweet from @elonmusk in the last 12 months and manually labeled tweets that referred to Musk's companies or were in response to his critics. We looked at both the tweet text and the context of the tweet (if that was part of a Twitter thread, for instance) for this classification.
