We like to believe that our social networks are indifferent platforms that don’t play with our feelings the way our friends can. In reality, Facebook strictly controls every factor of its website’s experience—it’s far from impartial. So why not take control into our own hands? Artist Lauren McCarthy’s [Facebook Mood Manipulator](http://lauren-mccarthy.com/moodmanipulator/) gives you access to the same technology that the study used to control its subjects emotions. A sliding scale on the website allows users to select what kinds of posts they want, with factors including positive, emotional, aggressive, and open. Turn the positive slide all the way up, and all that appears are happy posts. Turn it down, and negativity replaces all the good vibes. McCarthy’s app suggests a kind of self-censoring. If you’re feeling down, then maybe you don’t want to see anything sad in your feed. Sure, the app performs a neat trick by scanning posts for emotive keywords and filtering them based on that vocabulary, but it also has a deeper meaning. It shows just how much our lives are contingent on what we experience online—we’re not communicating on social networks so much as living through them. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/2954664/manipulate-your-own-mood-before-facebook-does/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/2954664/manipulate-your-own-mood-before-facebook-does/"},"headline":"Manipulate Your Own Mood, Before Facebook Does","datePublished":"2014-07-03T20:00:39.000Z","dateModified":"2026-04-13T07:11:23.585Z","description":"But how do you mute engagement photos?","url":"https://time.com/2954664/manipulate-your-own-mood-before-facebook-does/","keywords":["Newsfeed","Social Media","facebook","Art","emotions","Design"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt357b6ea7e8c73e2a/69869a84361760182690ced8/closeup3.png?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Kyle Chayka","jobTitle":null,"url":"https://time.com/author/kyle-chayka/"}],"articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt357b6ea7e8c73e2a/69869a84361760182690ced8/closeup3.png?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"closeup3","caption":"","creditText":"Lauren McCarthy","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/tag/time-section-newsfeed/","name":"Newsfeed"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/2954664/manipulate-your-own-mood-before-facebook-does/","name":"Manipulate Your Own Mood, Before Facebook Does"}}]}] ```
