Analysis of Trump's tweets shows he's sleeping less, and getting angrier
Columbia University economics professors Douglas Almond and Sim Min Du use President Trump's tweets from January 24, 2017 to April 10, 2020 as indicators of 'sleep time.' And analyzed. Normally, President Trump started tweeting at 6 am, posted once every two to three hours, and the average number of tweets per day was 10.
President Trump's behavior of waking up around 6am every morning is consistent between 2017 and 2020, while Twitter activity between 11pm and 2pm has increased by 317%. understood. Shortly after taking office, President Trump posted late-night posts about once a week, but in April 2020 it increased to three times a week. Studies show that the average posting time three times a week is 0:06 midnight.
In the graph below, the vertical axis shows 'average number of tweets within 30 minutes' and the horizontal axis shows 'time'. Looking at the graphs for 2017 (blue), 2018 (red), 2019 (green), and 2020 (orange), the times when the number of tweets starts to increase are almost the same.
On the other hand, if you limit the horizontal axis from 22:00 to 7:00 am, you can see that the number of posts from 22:00 to 1:00 am increased in 2019 and 2020 than in 2017 and 2018. ..
The Centers for Disease Control and Prevention recommends 7-8 hours of sleep for adults over the age of 65, but the study estimates that President Trump sleeps at least 6 hours three days a week.
Researchers also revealed that the day after they tweeted until midnight, President Trump's tweets averaged 7,400 fewer likes, 1,300 fewer retweets, and 1,400 fewer replies. This means that the performance of tweets is 6.5 to 8% less, and it tends to be difficult for people to post content that resonates.
In addition, when 'emotion' was analyzed from the words contained in the tweet, 'happiness / satisfaction' accounted for 88% of all President Trump's posts, but the day after the day when he posted until midnight, , The percentage of 'happiness / satisfaction' was shown to decrease by 5%. Instead, the proportion of 'anger' has increased by 3%.
This is a graph with the ratio of emotions such as happiness and satisfaction to tweets on the horizontal axis and the time from 2017 to 2020 on the horizontal axis. In 2020, the graph has picked up a little, but other than that, it can be seen that it has been declining consistently since the inauguration of the president.
The results of this study are based on President Trump's public schedule and Twitter posts, but keep in mind that they don't always match actual sleep times. However, researchers said, 'In our study, shorter sleep times during the president's first term and the pattern of poor performance due to lack of sleep were part of it.' 'If the president's sleep time is optimized.' If not, this is a problem to be solved. '
