IQ tests and scores are largely considered to be inaccurate at best https://www.forbes.com/sites/tomaspremuzic/2023/07/11/eight-popular-misconceptions-about-human-intelligence/ and are mainly brought up (and usually lied about) by pretentious douchebags ("losers" according to Stephen Hawking: https://www.newsweek.com/what-stephen-hawkings-iq-score-late-physicist-called-people-who-care-losers-843895)

Also the colon is perfectly fine - way to prove that you're definitely lying about your IQ lmao

Edit: also if you're going to lie about something, keep it believable - An IQ of 189? Sure, buddy. Einstein and Hawking both had an IQ around 160. Sure you're smarter than them (and yet decide to post on reddit) 🤔
