The test helped identify "issues with the system" which will be addressed by next week according to Elon Musk.
Ian Miles Cheong, a right-wing commentator, had tweeted about a similar test and found that a tweet sent when his account was set to private had a higher reach.
Elon Musk was concerned by this result and decided to conduct his own test.
He made his account private for 24 hours to see if his private tweets would be seen more than his public ones.
He has conducted several experiments on the social media platform since then, including using Twitter polls and changing the timeline to a default algorithmic feed.
Elon Musk continues to be a prominent and influential figure on social media, with millions of followers.
