Document Summary
Gaining knowledge by direct observation or personal sensory experience. In the real world there are often several possible explanations for an outcome, alternative explanations called confounds. Personal experience often does not involve a comparison group (usually just based on observations of self) A comparison group allows a person to compare what would happen with and without the thing they are interested in (e. g. , energy drink, violent video game), in a systematic and unbiased way. He didn"t have a group where he didn"t slit wrists so he wasn"t sure why people were dying. Accepting ideas as valid because they feel true/right, you have biases in our intuition. Catharsis sounds like a good story, so it must be true" - not always the case! Maybe not on purpose (mostly not aware that we do this) Ex: always being late, only going to remember when the person is always.
