All rise, the Twitter court of public opinion is now in session. And the next case on the docket will reach a quick verdict. Because public opinion solidifies rapidly on Twitter. That's according to a study in the journal Chaos. Researchers collected almost 6 million tweets during a six-month period. They sorted the tweets for either positive or negative sentiments, then focused on three topics related to electronics. At first opinions fluctuated, with one side gaining a slight advantage. This advantage grew gradually and then quickly leveled off, leaving one opinion in a stable and dominant position—but without an overwhelming consensus. And once public opinion is established, it is unlikely to change. Only those who see a large number of descending opinions among the people they follow on Twitter will reconsider and examine the opposing viewpoint.
