" My point is that perceptual bias can affect nut jobs and scientists alike. If we hold too rigidly to what we think we know, we ignore or avoid evidence of anything that might change our mind. "
- Martha Beck

Perceptual bias can influence anyone, from those with extreme viewpoints to respected professionals like scientists. The quote emphasizes that when people become overly attached to their beliefs and knowledge, they tend to overlook or dismiss any information that challenges these views. This tendency creates a barrier to learning and adapting based on new evidence.

The deeper meaning of the quote suggests that being open-minded is crucial for personal growth and scientific discovery. It highlights how clinging too tightly to one's preconceived notions can lead to missing out on valuable insights and opportunities to improve understanding or change flawed beliefs. Moreover, it underscores the importance of being receptive to diverse perspectives and data in order to achieve a more accurate and comprehensive view of reality. By embracing flexibility and openness, individuals can foster an environment conducive to innovation and progress.
