Principles of CBT

1. Moods are created by thoughts.

2.  Bad moods are created by negative thoughts.

3. Negative thoughts result from irrational thinking.

Here are some fallacies that indicate irrational thinking, albeit not the ones typically discussed in CBT literature.

Survivorship bias: overestimating one's chance of success based on the success of persons who have passed a selection process while ignoring the failure of those who did not.

Swimmer's body illusion: confusing the factor of selection with the result, for example concluding swimmers have great bodies because they swim, rather than concluding that swimmers swim because they have bodies fit for it.

Clustering illusion: mistaking random data for patterns.
