In IHP SLOTS polling in October, all major party leaders continued to have negative favourability ratings. But NPP/JVP leader A.K. Dissanayake saw his ratings improve to -9 (up 10 points). The favourability ratings of the other leaders declined. SJB leader, Sajith Premadasa’s favourability dropped to a new low of -66 (down 13 points) reaching similar levels to President Ranil Wickremasinghe whose favourability dropped 8 points to -65.
Favourability estimates for each month are based on 100–500 interviews conducted during that month and during a few weeks before and afterward to ensure a minimum set of responses. The October 2023 estimates are based on 394 (Sajith Premadasa), 358 (A.K. Dissanayake), 387 (Ranil Wickremasinghe), and 179 (Gotabaya Rajapaksa) interviews.
Note to editors
We have noted that some members of the public misunderstand media reporting of these numbers. 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.
IHP is an independent, non-partisan research centre based in Colombo, Sri Lanka. The SLOTS lead investigator is Dr Ravi Rannan-Eliya of IHP, who has trained in public opinion polling at Harvard University and has conducted numerous surveys over three decades.
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.
The SLOTS has been funded by the Neelan Tiruchelvam Trust, the UK National Institute for Health and Care Research (NIHR), The Asia Foundation in Sri Lanka, and others, but the sponsors play no role in the study design, analysis, or interpretation of findings. Interested parties can contact IHP for more detailed data and results.
