Most of these crises are self-made, the result of human decisions, and their acceptance/toleration by society. Policies and practices at all levels of society that created, exacerbate and launch new crises are, at worst, self-serving and, at best, faulted through a lack of understanding. In democracies, citizens can hold decision-makers to account but, to do this, they must understand the issues and be able to imagine better policies. We also live in a digital world in which a flood of mostly inconsequential information and misinformation pollutes our brains, enhancing pre-existing biases and creating new ones, and numbing our mental ability to think clearly and reach sensible decisions. But sensible decisions are urgently needed at all levels to fix problems and reduce future self-harm. Sensible decisions require sourcing the best available relevant information, and a process to convert information into understanding, understanding into clear decision options, and the choice of a decision option that leads to an action that represents best practice. Critical thinking is the enabling cognitive process of this decision pathway, because it selects the best available information through demanding evidence-basing, seeks critical discourse between experts and stakeholders that agnostically explores solution space to find plausible options, and whittles down options inter alia through plausibility, due diligence, bottleneck analysis, cost-benefit analysis, and benchmarking filtering. Crucially, it rejects biases, influencing factors, and other constraints on options, and is an effective barrier to the information flood. The problem is that critical thinking capacity is not widely available among either decision makers or stakeholders. There is an urgent need to rapidly roll out effective education programmes in which critical thinking teaching is solidly embedded. Since biases accumulate with age, the teaching of critical thinking must begin with the very young. However, the very young are not able to comprehend the complex abstract issues underpinning critical thinking. Embedding the teaching of critical thinking in a suitable educational context, and integrating it into curricula, is another challenge. To address these two challenges, the International Microbiology Literacy Initiative is developing a storytelling programme for children, called the Critical Thinking MicroChats Gallery, within the curriculum of societally relevant microbiology it is creating. MicroChats illustrate the principal practical elements of critical thinking, like bottlenecks, cost: benefit, benchmarking, the need for discussions and other points of view, employing readily relatable, relevant microbially centric scenarios. MicroChats suggest class discussion topics to encourage children to imagine the application of each element in other contexts to reinforce principles and hone critical thinking skills. Critical thinking, and especially the cultivation of the habit of asking 'why' and requiring plausible justification for policies/actions, is a shield against bias, prejudice, propaganda, misinformation and the incessant pressures of social media. It promotes a healthy mind and the attainment of the developmental potential of individuals. Increasing critical thinking in society will raise the quality of decision making at all levels and thereby improve sustainability/reduce the human footprint on our planet, and promote the individual sense of responsibility and global citizenship necessary for the improvement of the condition of humanity and its relationship with Planet Earth.PMID:41396129 | PMC:PMC12704398 | DOI:10.1111/1751-7915.70270
