Methodology
The ranking above is based on a reading comprehension test known as Simple Measure of Gobbledygook (SMOG). The SMOG test measures the number of three syllable words used in a text to calculate the years of education required to understand it. An environmental activist, DiCaprio often tweets about “conservation” and global warming which may have helped him earn the top spot.

In a recent analysis of more than 1 million tweets, we found that messages on Twitter average a fourth-grade reading level. All of the celebrities above exceed that grade. To find Twitter’s smartest celebrities, we analyzed the last 20 tweets from the 500 highest followed celebrities (stripped of URLs and hashtags), then ran the results through the SMOG test to calculate reading level. SMOG is intended for processing English, so users tweeting in multiple languages were removed. Computer processing of natural language has its limitations. For example, the SMOG test can falsely read slang as multi-syllable words.

You can test your own Twitter grade level or anyone else’s here.

How Smart Are Your Tweets?

Thirty-three percent of tweets test at a fourth grade reading level. Use the tool to see how yours compare.

Justin Bieber may have celebrated his 20th birthday this spring but on Twitter, he isn’t smarter than a fifth grader. The rebellious Canadian pop star shouldn’t be embarrassed: Lady Gaga is also tweeting at fifth grade level, while President Barack Obama doesn’t score much higher: he tweets like a seventh grader.

According to TIME’s analysis of 1 million public tweets, 33 percent of tweets test at a fourth grade reading level. The test relied upon a commonly used reading comprehension survey known as SMOG, or Simple Measure of Gobbledygook (really), to assess the complexity of messages sent on the social network. “Gobbledygook” is defined as a word of three or more syllables.

Who uses the most gobbledygook? You guessed it: politicians. Search for lawmakers like @NancyPelosi and @SpeakerBoehner to see how they measure up, or use the tool to find the reading level of any public twitter account.

SMOG results show that most tweets require no more than a fourth grade education to comprehend. Of course, a tweet’s limit of 140 characters makes it difficult to compose a message at a higher reading level. But not impossible. This test did pick up a handful of 12th-grade tweets, like this one from a senior curator at the Museum of Modern Art: “Design and violence: Nivedita Menon’s powerful essay on the mini-revolver marketed to women by the Indian government.”

Methodology

Tweets were downloaded with the Twitter API and run through a version of the SMOG test written for JavaScript. A search of a public account returns the 20 most recent tweets from that account. The page considers all of those tweets together as one long paragraph, which leads to higher accuracy than average the score for each tweet.

Which World Cup Team Is the Most Valuable?

The Spanish team is worth more than $900 million—9.5% of the market value on all World Cup players

On Thursday, FIFA announced the 23 players for each of the 32 World Cup teams. All put together, these 786 players have a total market value of $9.69 billion, according to the trading site Transfermarkt. The priciest squad taking the field in Brazil this month? Spain. The scrappiest? Honduras. The Spanish squad’s players have a market value of $916 million, representing 9.5% of the total market. That’s nearly 34 times the Honduran team’s $31.1 million value, which accounts for 0.32% of the market.

Use the interactive below to compare values between teams and their players. Click on club teams to see which professional teams have sent players to the global tournament.

Player market value is determined by many factors like individual and club team performance, international experience, contract history and age, which in part explains why Lionel Messi (26) is worth $177 million while Cristiano Ronaldo (29) is worth $147 million.

How Often Does Your College Report Sexual Assaults?

High numbers of reported assaults are often a sign a college is doing a better job addressing the issue. See the interactive below to compare schools' reporting

The prevalence of sexual assault on college campuses is often masked by low levels of reporting, as Eliza Gray reported in a recent TIME cover story. Despite the troubles with reporting, comparing the number of incidents that are recorded on campuses can be instructive. In the interactive below, you can search for your school to see how many sexual assaults it reported between 2006 and 2012.

Counterintuitive though it may seem, a higher number of reports from an institution is often a good sign, because it means the school is doing a better job than others at addressing the issue. According to research from the Department of Health and Human Services [pdf], nearly one in five women is the victim of sexual assault or an attempted assault while attending college. Reporting levels for all schools are well below that number.

All schools that receive federal funding must submit annual security reports to the Department of Education, and the White House recently pressured universities to address the problem more proactively.

In 2012, the most recent full year on record, 4-year non-for-profit and public institutions averaged 1.8 reported assaults. The 55 schools currently facing Title IX sexual assault investigations averaged 12 reported assaults in 2012. The ten schools with the highest number of reported assaults average 27.9 in 2012. As the chart shows, the number of reported assaults is on the rise at many institutions.

Here are the top-ten schools with the highest cumulative reports of sexual assault from 2006 to 2012. Again, high reports don’t necessarily mean the highest levels of the crime.

  • Ohio State University-Main Campus, 248
  • University of Michigan-Ann Arbor, 208
  • University of California-Davis, 206
  • University of California-Los Angeles, 168
  • Harvard University, 152
  • Indiana University-Bloomington, 149
  • University of California-Berkeley, 143
  • Pennsylvania State University-Main Campus, 136
  • Dartmouth College, 125
  • Princeton University, 122

Numbers show on-campus and off-campus forcible and non-forcible sexual assaults.

Methodology

Forcible and non forcible sexual assaults are available from 2006 to 2012 from the Department of Education’s annual security reports. This includes on-campus security reports, such as dormitories and school buildings, and non-campus security reports like Greek housing. Schools are filtered by four-year private not-for-profit schools and public schools.

How Popular Is the Sound of Your Name?

Noticed a lot of J names in your life? It's not a coincidence. Use this searchable graph to find out how popular your name's sound is

See TIME’s Baby-Name Predictor

Flip through your contacts and odds are you’ll find a few Jessicas, Jennifers and Johns. Until very recently, the soft g — found at the beginning of most J names and G names like George and Ginnie — was by far the most popular sound used in baby names in the U.S.

Just as individual names rise and fall in popularity, researchers have found that the sounds (or phonemes) used in names also go in and out of fashion. Up until 2008, the names beginning with a soft g had the largest share among the 36 phonemes, going back all the way to 1880, when the data from the Social Security Administration begins. It was finally overtaken by the k phoneme, found in Katie, Christina and Kevin.

Each line on the graph above represents one phoneme’s percentage of names in each year. While the soft g (identified as jh) and k phonemes still have the highest number of names, they are steadily declining while those like xo (Xavier and Zander) and ao (Oscar, Aubrey) are on the rise. These changes reflect a broader trend of increasing distribution of names among phonemes. In 1880, jh owned 29% of the market. Now it only holds 13%. As America becomes increasingly diverse, so does the sound of its names.
