Step-by-step explanation:
Being intellectually persevering is important for a critical thinker because it helps them overcome biases and avoid falling into the traps of easy, automatic thinking. By persisting in their thinking and actively challenging their own beliefs and assumptions, critical thinkers are able to resist cognitive biases and engage in critical reflection. This allows them to arrive at more accurate and informed conclusions.
