This short note proposes using FIKR (Facet, Insight, Knowledge and Resilience) personality traits (PTs) to understand human behaviours regarding Fukushima wastewater discharge and provide a potential human psychological solution. The FIKR PTs are proposed to provide a framework for understanding and addressing human behaviours and concerns regarding the Fukushima wastewater discharge. By recognizing the FIKR PTs, we can engage in informed discussions, consider opposing viewpoints, and develop comprehensive solutions considering the potential risks and benefits of the Fukushima wastewater discharge. This approach will help protect public health and the environment and promote sustainable practices for future generations.
