Virality on Twitter is catching the attention of researchers, trying to identify factors which increase or decrease the probability of retweeting.

We focus on the Spanish political situation during the pseudo-referendum held in Catalonia on 1 October 2017. We have found that the use of negativity in a tweet increases the probability of retweeting and that iSOL lexicon is the one that better determines the relationship between polarity and virality.
