Reality versus your perception
"Reality" is the actual being of any thing; truth; fact; in distinction from mere appearance. Your worldview is your perception of reality: how you think the world works.
These are two different things:
You determine your perspective
You decide which facts you:
The truth versus your desired appearance
The ensuing frame of reference is your worldview. And it's your choice to either:
Either the truth...
Aligning your worldview to reality is simple. You must allow your view to be corrected by the truth. For this purpose, make sure that your standard of evidence is realistic.
...Or your desired appearance
If you want to embrace your view in spite of truth, you embrace a lie. Notwithstanding, you can persuade yourself that your view is true.
You can do this by:
In addition, you can validate your view with supporting evidence ("cherry picking"). This will yield self assurance. However, you select this evidence by the standard you seek to validate. This is self-referential. And validating your view by your view is circular reasoning. And self deceit.
In other words...
"Worldview validation", in spite of truth, translates into "self justification" in spite of truth. This requires willful ignorance and circular reasoning: validating your view by your view. Etcetera.
Self justification requires willful ignorance, which is self deception.
By using your personal worldview as your private measure to confirm your worldview (self justification), you commit a form of circular reasoning (willful ignorance), which is a fallacy that gives you false assurance (self deception).
By embracing this false assurance, you are deceiving yourself. But this self deception occurs outside of your awareness. Even if you think you know, you actually don't know. Otherwise, you would not be doing it.
This however is only realized when your circular reasoning for self justification is no longer sustained. This can happen by personal choice or by personal failure, which will happen inevitably at the moment you die.
A hypocrite without knowing it
If self justification is your aim, you need to be willfully ignorant to achieve it. The required willful ignorance ensues from the adjustment of your standard of evidence to justify either:
By doing so, you are feigning to be true what in reality is not true. This is hypocrisy. And by reason of your ensuing willful ignorance, it follows that you, being a hypocrite, are not aware of your hypocrisy. For if you would acknowledge your hypocrisy, you would no longer be feigning to be true what in reality is not true. And then you would no longer be a hypocrite.
