Contrast Trump's gaffes with Biden's misspeaks

6. telescoping

Good post Goth, agree completely both you and evan;

Joe Biden: Said he met with Parkland kids while he was VP (Parkland happened 2 years after he left office)

This is known as 'telescoping' (iirc), where events from the past are usually remembered & slightly displaced closer to current time, than when they actually happened (or a different time).
Can & does happen to normal people as we age, usually subconsciously, sometimes intentionally.

Joe Biden: - Said: “Poor kids are just as bright, just as talented, as white kids.”

Unfortunate slip. Vice President Biden misspoke and immediately corrected himself

Joe: - Said: “We choose truth over facts.

Obvious he misspoke.
There are two ways to compare transgressions & other serious matters. First by severity of transgression, second by relative frequency of transgressions of similar severity.
Both by worst severity & higher relative frequency of transgressions, Trump wins.
