The Barnum Effect is strengthened when people believe the statements are unique and specifically created for them.

If you think a statement was carefully crafted just for you, you're much more likely to believe it. This is why psychics or online quizzes often ask for personal details like your birth date or favorite color. These details aren't used to generate a truly unique reading; they simply make you *feel* like the reading is personalized. This 'personal validation' makes you drop your guard and actively look for ways the vague statements apply to your life, even if they're actually generic.
