Passage Summary: A psychologist argues that brown-nosing doesn't actually get you promoted because bosses can almost always tell when you're being a suck-up.

Conclusion: Flattery is generally not the reason why employees who flatter their supervisors get promoted.

Reasoning: Most flattery is so obvious that the supervisors being flattered are aware of it.

Analysis: The psychologist’s argument has a glaring gap: it assumes that if a boss *notices* flattery, the flattery won't work. This is a bold assumption about human ego; some supervisors might actually enjoy blatant flattery even if they know it's insincere. To make the conclusion follow logically, we need a 'bridge' premise that connects the awareness of flattery to its failure. Look for an answer that explicitly states that flattery fails to achieve its goal whenever it is recognized as such by the target.
