Mind the Gap: Heritage, Evolution, and the Human Quest for Certainty in an Uncertain World

This article investigates the informational completion mechanism of the human mind, through which the brain fills cognitive gaps to create a coherent narrative continuum and eliminate uncertainties. The study aims to analyze whether this process relies solely on immediate experiences and direct learning or if it also includes deeper influences passed down from a transgenerational past and even from the evolutionary stages of species. The central question of the research is: Do we use only recently accumulated information to fill knowledge gaps, or does our brain access a broader fund, imbued with subconscious legacies and evolutionary predispositions? This exploration seeks to reveal how cognitive biases, such as the anchoring effect and confirmation bias, contribute to building an adaptive informational framework intended to support psychological stability and perceptual coherence. The paper also examines how these automatic completions can give rise to beliefs and myths that fill knowledge gaps, reinforcing an overarching narrative. Through informational completion, the brain not only stabilizes an individual’s subjective reality but also shapes common worldviews that support social cohesion and collective identity. The findings suggest that the cognitive completion mechanism, far from being merely adaptive, represents a quest for certainty and stability in the face of the unknown. In a rapidly changing world, this capability becomes essential for human adaptability. However, the question remains: To what extent does this informational fund accessed by the mind extend, and what role do the collective subconscious and evolutionary influences play in the cognitive completion process?
