To verify their findings and check if English is inherently positive or negative, the scientists analyzed billions of words from Twitter, a half-century of music lyrics, 20 years of The New York Times, and millions of books going back to 1520.
After finding the 10,222 most frequently used English words from these four sources, they asked a group of volunteers to rate the emotional temperature of these words. […]
RESULTS: There was an overwhelming preponderance of happier words among the top 5,000 words in each of the sources.
CONCLUSION: English is strongly biased toward being positive.
