Dissanayake fell 15 points to -44 points in July while SJB leader Sajith Premadasa’s favourability rating increased 4 points to -44 points. President Ranil Wickremasinghe’s favourability rating remained the same (-52). Favourability estimates for each month are based on 100 to 400 interviews conducted during that month and during a few weeks before and afterwards to ensure a minimum set of responses. The July 2023 estimates are based on 367 (Sajith Premadasa), 309 (A.K. Dissanayake), 367 (Ranil Wickremasinghe) and 154 (Gotabaya Rajapaksa) interviews. Negative scores, i.e., a net favourability rating of less than zero, means that the individual or institution is unpopular. Only positive scores, i.e., net favourability is more than zero, mean that the individual or institution is popular on average. Methodology SLOTS surveys a national sample of adults (ages 18 and over) reached by random digit dialling of mobile numbers, and others coming from a national panel of respondents who were previously recruited through random selection. SLOTS tracks favourability by asking respondents if they have a favourable or unfavourable opinion of a public figure or institution: net favourability being the average of the positive (+100) and negative (-100) responses. All estimates are weighted to match the national population with respect to age, sex, ethnicity, socioeconomic status, sector, province and past voting preference. Monthly estimates are based on samples of 100+ interviews pooled from interviews in each month and from weeks before and afterwards.
