In 2016, media outlets began conducting dual-frame random digit dialing(RDD) surveys that sample mobile phone numbers in addition to the traditionaltargets with landline phone numbers. The resulting greater outreach to hitherto underrepresented youths and mobile-only users has improved the credibilityof polls. Still, new challenges have been identified with surveys targetingmobile phone users. Examples include a predominant share of males amongrespondents and the difficulty in ensuring validity of survey caused by inconsistencywith methods used for surveys that target only landline phone users.Unfortunately, there are no promising alternatives for opinion polling in caseRDD surveys grow difficult. Worse still, failures in predicting election resultsand mistrust of the media have dampened confidence in polls. Going forward,pollsters must gain people’s trust regarding opinion polls by properly explaininghow they are supposed to be conducted.
