Self-deception begins within seconds of listening or speaking.
Once committed to an interpretation or tending toward one, the brain builds on it quickly.
Once an interpretation has been built upon, the brain remembers it as what truly happened even if that is false.
This is normal. The human brain has evolved to use self-deception.
This probably happened because truer forms of communication are complex and use a lot of time. They can also be confusing and difficult.
Confusion, difficulty, and complexity interfere with social cohesion and motivation.
Strong self-deception deceives others better than weak self-deception or no self-deception. In this way, it promotes social cohesion and motivation.
Self-deception can be observed and understood if it is caught quickly. The best way to catch it is through a technique like FIML.
Self-deception is a kind of neurosis, delusion, false cognition. Nevertheless, we are so used to it, we can feel lost without it.
If self-deception is discovered many times through FIML practice, it does not present as a philosophy or attitude or whole picture of the mind. Nor does it present as a neurosis, delusion, or false cognition.
Rather it presents as a composite of many pixels—many small instances—of observed and corrected mistakes.
Thus seen as an aggregation of many small instances, self-deception gradually is lessened.
