In an era of rapid global change, critical thinking stands as the driving force behind societal transformation, paving the way for both innovation and effective governance. This research peruses into the enduring significance of Karl Popper’s critical rationalism, championing open societies, and a break from dogmatic thinking. The spotlight is on Nigeria’s socio-political terrain, investigating the power of critical thinking as a catalyst for rational governance.
Through a hermeneutic lens, the paper explores Popper’s concept of falsifiability, shedding light on its potential to challenge entrenched systems as Nigeria seeks democracy and development. The study exposes the roadblocks of rigid ideologies, manipulative politics, votebuying, “relevance by association,” the get-rich-or-die-trying mentality, the neglect of rural communities, widespread poverty, and a faltering education system, all of which impede progress. It contends that infusing Popper’s philosophy into Nigeria’s educational, political, and social frameworks could nurture a more equitable, open, and rational society. The work advocates for a thorough overhaul of these sectors, promoting continuous questioning and innovation as keys to sustainable progress and transformation.
