Deliberate ignorance is a potential barrier for information interventions aiming to reduce meat consumption and needs to be considered in future interventions and research. Self-efficacy exercises are a promising approach to reduce deliberate ignorance and should be further explored.

Which theory of behavior change can help you plan a health communication intervention for a large audience? There is no single right answer, but some theories will fit your needs better than others. The purpose of this tool is to rank-order some commonly used theories by their degree of fit with your behavior change challenge.

There are surely many ways in which our beliefs can be quite nuanced. We examined the different ‘styles’ of belief we come up against in a variety of the work we do and observed a number of ways these styles appear: Suspension of disbelief: We know not to look too closely at something – we think that overall it is a good thing (e.g. recycling) but aware of possible discrepancies (e.g. being poorly disposed of) that may or may not lead us to question our positive beliefs. We are aware of the possible conflicts but this does not make our belief in the value of recycling any less valid. There are a great many beliefs that we have that could be challenged yet they serve us sufficiently well that we do not need to interrogate them too closely (political representation, eating meat) Inconsistent beliefs: Linked to this, we may hold two conflicting beliefs at the same time. We may know that wild fires are a natural phenomenon that predates climate change; but also that the fires we see in many areas today are of a much greater intensity and frequency. Exactly which is responsible cannot really be picked out, we can only really see the patterns emerging at a more macro-level, so it is not unreasonably to either hold both as true for even consider that the fire you have experience is a normal wild fire. Off-loading beliefs to others: Much of the time our beliefs about how things work is not something that we each individually work out, but we rely on a community of knowledge to work on our behalf. How many of us can be sure that our beliefs are correct about how vaccines work or indeed even how a zipper work. If we are questioned, then we recognise that our belief about how something works is tenuous but we have a good enough sense of it that allows us to function. Unformed beliefs: Sometimes we have not quite worked out what our beliefs are about something, which means that we may well move about in those beliefs or in the strength to which we hold onto them. The vaccination example outlined earlier is a good case in point. Not sure fully believe it but ‘there is something in it’ beliefs: Recent work we have been doing on Conspiracy Theories suggests that people may consider something is believable (e.g. Princess Diana’s death in a car crash was not accidental) but at the same time, in a different question then say they ‘do not fully believe it but there is something in it’. So what might seem like a belief is actually something much more akin to a questioning stance.

The Patient Activation Measure is a valid, highly reliable, unidimensional, probabilistic Guttman‐like scale that reflects a developmental model of activation. Activation appears to involve four stages: (1) believing the patient role is important, (2) having the confidence and knowledge necessary to take action, (3) actually taking action to maintain and improve one's health, and (4) staying the course even under stress. The measure has good psychometric properties indicating that it can be used at the individual patient level to tailor intervention and assess changes.

Often, there's a disproportionate focus on pre-existing attitudes or other exogenous factors explaining why behavioural interventions may not work. In other words, attitudes or other factors got in the way of the intervention being effective. But that's not necessarily the case, as this study suggests. Instead, it might be the nature of the intervention itself which blocks the behaviour (change).

Narrative is the basic mode of human interaction and a fundamental way of acquiring knowledge. In the rapidly growing field of health communication, narrative approaches are emerging as a promising set of tools for motivating and supporting health-behavior change. This article defines narrative communication and describes the rationale for using it in health-promotion programs, reviews theoretical explanations of narrative effects and research comparing narrative and nonnarrative approaches to persuasion, and makes recommendations for future research needs in narrative health communication.

This article reports on new research that finds certain messages reduce fear of sharks, key to promoting conservation-minded responses to shark bites. Here it is argued that the sophistication in public feelings toward these highly emotional events has allowed new actors to mobilize and given rise to the ‘Save the Sharks’ movement. In a unique experiment coupling randomly assigned intent-based priming messages with exposure to sharks in a ‘shark tunnel’, a potential path to reduce public fear of sharks and alter policy preferences is investigated. Priming for the absence of intent yielded significant fear extinction effects, providing a viable means of increasing support for non-lethal policy options following shark bite incidents. High levels of pride and low levels of blame for bite incidents are also found. In all, this article provides a step towards improving our understanding of fear and fear reduction in public policy.

The results lead to some useful messaging recommendations, such as active publics being more effectively moved to action through motivational frames, rather than diagnostic (i.e. problem-focused) or prognostic (i.e. solution-focused) frames.

A negatively framed message (i.e. which describes the behavior that should not be done) is more effective, at least in this context, than a positive framed message that describes the preferred behavior.

New research finds that people tend toward appeals that aren't simply more positive or negative but are infused with emotionality, even when they're trying to sway an audience that may not be receptive to such language. The findings appear in Psychological Science, a journal of the Association for Psychological Science
