Perception spillover shapes social licence trajectories in emerging industries
This paper demonstrates that the social licence of emerging industries, such as seaweed aquaculture, is critically shaped by perception spillover from established sectors, where positive associations can bolster support while negative ones erode it, highlighting the need for governance strategies that leverage favorable links and mitigate adverse ones.

When a new industry tries to take root in a community, its success often depends on more than just its own merits. It enters a world already shaped by the reputations of older neighbors. People do not judge every new project in isolation; instead, they carry over feelings formed by past experiences with similar activities. This psychological phenomenon, known as perception spillover, means that a positive or negative view of one thing can easily bleed into how people feel about another. For emerging sectors like seaweed farming, which rely on public trust to operate, understanding this invisible transfer of opinion is critical. If the public associates a new venture with a controversial predecessor, the new industry may struggle to gain acceptance, even if it is doing everything right. Conversely, linking a new project to a beloved community effort could help it flourish.
Researchers in Australia set out to test how these spillover effects shape the future of the seaweed aquaculture industry in Tasmania. They focused on a specific dynamic: how the public's feelings about two established marine activities—salmon farming and reef restoration—might influence their views on the emerging seaweed industry. Salmon farming in the region has been a source of significant debate and conflict, while reef restoration projects are generally viewed with warmth and support. The team wanted to see if the negative reputation of salmon farming could drag down the seaweed industry, or if the positive spirit of restoration could lift it up. To find out, they combined a large survey of 931 Tasmanian residents with detailed interviews with community leaders and a sophisticated computer simulation that modeled how opinions spread through a population over time.
The study revealed that the seaweed industry sits on a knife-edge, highly sensitive to these external associations. In the computer models, when the researchers simulated a scenario where news about salmon farming influenced public opinion, support for seaweed farming dropped sharply. The community became more divided, with conflict levels rising as people began to view seaweed farming as just another version of the contentious salmon industry. The simulation showed that even without any actual change in how seaweed farms operated, the mere association with salmon was enough to push the industry from a state of general acceptance into a contested, risky position. The public's certainty about their views increased, but in a negative direction, creating a barrier that the seaweed industry could not easily overcome with its own performance alone.
In contrast, when the models introduced the influence of reef restoration, the trajectory changed completely. Linking seaweed farming to the positive, community-driven work of restoring kelp forests and marine habitats strengthened public support. In these simulations, the seaweed industry moved toward a stable social license, where the community was not only accepting but actively interested in the industry's growth. The conflict levels remained low, and the public viewed the industry as a partner in healing the ocean rather than a threat. The researchers found that the direction of the spillover mattered more than the industry's own actions. A favorable starting point was not enough to protect the new industry if the public was already primed to see it through the lens of a controversial neighbor.
The team also tested whether communication strategies could fix the damage caused by negative spillover. They simulated campaigns using persuasive advertising, which often backfired by increasing conflict as different groups dug in their heels. However, strategies focused on education and collaboration worked much better. When the model included efforts to improve general ocean literacy or bring stakeholders together to learn from one another, the community became more resilient. These approaches reduced the intensity of the conflict and helped buffer the industry against the negative effects of the salmon association. The simulation suggested that while industry reforms and better performance are necessary, they are not a silver bullet; the most effective way to secure a future for the industry is to actively manage the narrative and inoculate the public against negative associations before they take hold.
Ultimately, the research highlights that the social license for an emerging industry is not just earned through its own environmental record; it is also inherited from the reputations of the activities that surround it. The study suggests that for new industries to succeed, they must be aware that they are entering a shared information space where the controversies of the past can dictate the future. In Tasmania, the path forward for seaweed farming depends on how well the industry can distance itself from the conflicts of salmon farming and align itself with the community's desire for restoration. The findings offer a clear warning to regulators and developers: ignoring the reputational weight of neighboring industries is a risk that can undermine even the most sustainable innovations.
