115 pages, Lab grown meat is a new technology being developed as a potential alternative protein source. Although some research has been done about public perception of lab grown meat, no studies to date have analyzed social media content regarding this topic. Still yet, no studies have observed the effects of message themes on public perception of lab grown meat. This two-part study first sought to analyze the Twitter messages discussing lab grown meat using Meltwater, a social media monitoring software. Secondly, the study sought to better understand measures of uncertainty and risk and benefit perceptions after viewing a themed blog post about lab grown meat. In part one, a relevant keyword search from August 28, 2018 to February 28, 2019 collected over 11,000 Twitter messages. Sentiment of messages was analyzed with 47% of messages being neutral. Meltwater identified trending themes that were all closely tied to lab grown meat, and top content posters with the most amount of potential reach were identified. All top posters were found to be news entities or organizations instead of personal Twitter accounts. In part two, participants were randomly assigned one of three themed blog posts against lab grown meat, neutral, or support lab grown meat. Perception questions were asked after viewing the blog post, and a total of 238 responses were collected. Results indicated message theme had a statistically significant effect on risk perception, benefit perception, and intention to share, but not on message evaluation or measures of uncertainty. Further discussion as well as suggestions for future research are included.
