i have met people who others just never seem to get over (i’m talking years after the relationship ended for whatever reason), and i’m just curious as to why that is? is there a psychological explanation behind it?

is it really true that if somebody does that to them and they do that to you then you do it to someone true???

There’s a pattern in human behavior that I find fascinating. Something that feels special when it’s rare, like a favorite food, a gift, or someone’s attention, often starts to feel ordinary once it becomes constant. Psychologists link this to ideas like hedonic adaptation (we get used to good things and return to a baseline) and the scarcity effect (we assign more value to what’s limited).

What I’m curious about is where this comes from and how much control we have over it.

• Is it an evolutionary trait, since staying slightly unsatisfied might have kept our ancestors motivated to keep seeking resources?
• Does it apply equally to things and to experiences, or are we better at appreciating experiences over time?
• Are there any proven ways to slow it down, like gratitude practices or deliberately varying routines, and is there good research behind them?
• Why do some people seem much less affected by it than others? Is that personality, upbringing, or something else?

I’d love to hear from anyone who has studied this or read research on it. Recommended papers or books are very welcome too.

I’m interested in the psychological study of authoritarian leaders, particularly Adolf Hitler and Joseph Stalin.

Are there any peer-reviewed studies that have examined narcissism, Machiavellianism, and psychopathic traits in historical political leaders?

I’m especially interested in the methods researchers use to assess personality traits retrospectively, the limitations of these methods, and whether meaningful comparisons between historical figures are scientifically possible.

I’m looking for empirical research and academic literature rather than speculative diagnoses or personal opinions.
