What we think we know and what actually is are two very different things. When we search we must allow the trail of evidence to take us and reveal to us what is actually there, not what we think we know might be there. Confirmation bias can be a dangerous thing because it allows us to make decisions about what we already think we know. Preconceived ideas lead us only to prejudice, not to knowledge or true understanding. We must look at the evidence of things for what they are - a raw and real proof of the truth we seek.
