We have methods to extract arguments that represent different stances on an issue (Misra et al., 2016a;Anand et al., 2011;Sridhar et al., 2015;Walker et al., 2012a;Walker et al., 2012b), as well as argument exchanges that are agreements vs. disagreements , factual vs. emotional arguments (Oraby et al., 2015), sarcastic and not-sarcastic arguments, and nasty vs. nice arguments (Oraby et al., 2016;Lukin and Walker, 2013;Justo et al., 2014).
as expected, opinion change is greater for people who are initially more neutral about a topic, than those who are entrenched.
