This included Google Books, Twitter, subtitles on films and TV shows, song lyrics and the New York Times in Spanish, Chinese, English, French, Portuguese, Arabic, Indonesian, Korean, Russian and German.

From this, the scientists compiled a list of 10,000 most commonly used words in each language and labelled each as either positive and negative. For example, the words ‘lying’ and ‘cried’ were plotted on the negative side, while ‘love’ and ‘laughter’ were positive words.

Once all of these words were plotted, the researchers found that every language studied was inherently positive, and more words fell on the right of centre than the left. ‘Using human evaluation of 100,000 words spread across 10 languages diverse in origin and culture, we present evidence of a deep imprint of human sociality in language,’ said the study.

‘The words of natural human language possess a universal positivity bias, the estimated emotional content of words is consistent between languages under translation, and this positivity bias is strongly independent of frequency of word use.'

And at the top of this list was Spanish, which had the highest skew towards positive sentiment. Chinese was at the opposite end of the scale, leaving English in third place.

The site has created an interactive ‘World of Love’ map that reflects the volume of messages mentioning this phrase in 100 different languages. You can find it on their website.
