Targeted Interception Theory of Behaviour Change: A New Basis for Effective Interventions in Tourism

Most behaviour change interventions work by providing information: a sign reminding guests that most visitors reuse their towels, a message about the carbon cost of a flight, an appeal to environmental values. Yet fewer than 60% of such interventions succeed. This conceptual paper argues that the problem is not the messages themselves but the assumption behind them — that behaviour is preceded by mental processing. When it is not, information has nothing to act on. The Targeted Interception Theory of Behaviour Change proposes matching the type of intervention to how much thinking actually precedes a given behaviour.

How the research was done

The paper is a conceptual contribution that sits between two recognised forms of theory-building: theory synthesis and theory adaptation. The authors synthesise established theories of human behaviour — the Theory of Planned Behaviour, Value-Belief-Norm Theory, Social Cognitive Theory — alongside theories of behaviour change such as classical and operant conditioning, script theory, and dual-process accounts of cognition. They then adapt this collective knowledge into a single framework. Rather than treating behaviour as either automatic or deliberate, the theory draws on the observation that action emerges from multiple systems, positioning any behaviour along a continuum of mental processing and conceptualising behaviour change as a long-term process disturbed by internal and external events rather than a single isolated incident. Tourism examples — towel reuse, opt-out carbon offsetting, daily room cleaning, a smoker denied their usual routine in a hotel room — anchor the argument.

What the research found

The theory identifies three broad types of behaviour distinguished by the extent of mental processing that precedes them, each requiring a different targeted interception. Considered behaviour — a couple choosing a new destination every year — involves substantial cognitive effort each time the behaviour recurs; here, providing information is a genuinely effective intervention, because information is precisely what the person is processing. Habitual behaviour sits at the opposite extreme: well-learned, cue-triggered, and performed with little or no conscious intent. Nearly half of everyday behaviour is estimated to be habitual, and for behaviour of this kind providing information is largely futile, because the information is never even noticed. To change a habit, the habit must first be disrupted. Scripted behaviour falls between the two — a mental road map, such as choosing among a handful of familiar holiday destinations, that requires some cognitive effort but far less than a fresh decision.

For habitual and scripted behaviour, the theory posits that some form of active interference or passive disturbance is required before information can play any role. A disturbance — a home relocation, a price change, a default switched from opt-in to opt-out, or simply the unfamiliarity of a first visit to a destination — forces the person back into mental processing, at which point they may abandon the old pattern, revert to it, or form a new one. This is where tourism becomes a distinctive opportunity: travel away from home is itself a disturbance, stripping away the stable contexts that sustain habits and scripts. Changing choice architecture works by the same logic, which is why asking guests to request room cleaning rather than opt out of it reduces daily cleaning by 63%. Crucially, the theory frames behaviour change as a long-term process: a disrupted habit may be replaced, but people can also snap back into their previous behaviour once the disturbance passes.

Insights for the industry

The practical implication is that the standard toolkit of information-based campaigns is being applied to behaviours it cannot reach. For any target behaviour, the first question is not what message to send but how much thinking precedes the behaviour in the first place. Where a decision is genuinely considered — a major, infrequent choice such as booking a trip of a lifetime — information and persuasion are well suited. Where the behaviour is habitual or scripted, effort is better spent engineering a disturbance: changing a default, altering the physical environment, or timing an intervention to coincide with a moment when the usual pattern is already broken.

Tourism is unusually well placed to act on this. Because travel removes people from the stable contexts that hold their habits in place, a hotel or destination is often intercepting behaviour at exactly the moment it has become malleable — the first stay, the unfamiliar routine, the absence of the usual cue. The same principle counsels caution: hard interventions such as price rises or legislation can be highly effective at disrupting habits but sit awkwardly in a sector where guest satisfaction is paramount, so gentle choice-architecture nudges tend to fit better. The authors are explicit that the theory now needs field testing, comparing interventions built on it against those derived from conventional theories of behaviour.
