This phenomenon is known as "belief perseverance".
Belief perseverance is the propensity for individuals to hold their convictions as obvious, notwithstanding when there is abundant confirmation to ruin the conviction. At the point when looked with confirm that negates their convictions, individuals may ruin, expel, misconstrue, or place little centrality on the conflicting information. Belief perseverance comes to fruition when individuals have a tendency to trust in specific things with an immovable confidence, and they decline to change those convictions notwithstanding when demonstrated off-base.
