Don't dumb it down: The effects of jargon in COVID-19 crisis communication.

Experts are typically advised to avoid jargon when communicating with the general public, but previous research has not established whether avoiding jargon is necessary in a crisis. Using the ongoing COVID-19 pandemic as a backdrop, this online survey experiment (N = 393) examined the effect of jargon use across three different topics that varied in situational urgency: COVID-19 (high urgency), flood risk (low urgency), and federal emergency policy (control). Results revealed that although the use of jargon led to more difficult processing and reduced persuasion for the two less-urgent topics (flood risk, emergency policy), there was no effect of jargon in the COVID-19 condition.

Jargon as a barrier to effective science communication: Evidence from metacognition.

In this experiment ( = 650), we examine the negative consequences of jargon on individuals' perceptions of emerging scientific technology and aim to explain these effects. We find that the presence of jargon impairs people's ability to process scientific information, and that this impairment leads to greater motivated resistance to persuasion, increased risk perceptions, and lower support for technology adoption. These findings suggest that the use of jargon undermines efforts to inform and persuade the public through the cognitive mechanism of metacognition.
