Self-Selection Bias: This occurs when individuals select themselves into a group, leading to biased results. It's like only chocolate lovers voting for the best ice cream flavor - of course, chocolate will win!
Sampling Bias:This happens when some members of intended population are less likely sampled than others. It's like asking only kids at an ice cream shop what their favorite flavor is - adults' preferences aren't considered.
Confirmation Bias:This is our tendency to search for and favor information that confirms our beliefs while simultaneously ignoring or devaluing information that contradicts our beliefs. Like believing chocolate is universally loved because all your friends (who also love chocolate) agree with you.
