Research Interests

Kathleen Hall Jamieson is interested in the ways that the language, content, format, structure and framing of messages affect attitudes and behavior. She and her colleagues have identified factors that affect audience understanding of candidate issue positions, climate-related trend lines, and the need for vaccination for measles. In experiments, they have shown that: media echo chambers affect their audiences' understanding of politics and political debates; the tactical framing of news activates audience cynicism and depresses learning; visually previewing, displacing and disclaiming misinformation increases the impact of corrections; and the effects of both endpoint and conservative ideological bias on perceptions of climate trends can be blunted through strategic messaging that reinforces the creditability of the scientific organization whose data is at issue, discloses the means by which scientists gathered the relevant evidence, iterates a complete trend line, and involves the audience in understanding the natural variability involved in climate- related trends.
Jamieson also has shown that the conventionalized structures of scientific reporting and the resulting news coverage of it can mislead the public about the nature of scientific practice, open science to compelling but unwarranted criticism, and undermine trust in science.
