This is a broad category meant to discuss all of the various methods used to try and influence your mood and emotional state. This is done to exert further control over the target usually with the goal of influencing how they respond to stimuli and ultimately to coax the target into making an actionable mistake. The most obvious and well known idea for this is kettling.

It does not need to be as severe or purposed as kettling. Often it is merely to try and influence another interaction. I.e. Buttering you up and making you feel great before a date with aHoneypot or trying to ruin your day to put you in a bad mood when you are interacting with someone they want to discourage you from talking to.

I have also heard about efforts to control when you have a “good days” and just trying make every other day bad until you Cave.

This mostly gets referenced in songs or if you’re scheduled for a “good day” perps will say “have a good day” instead of the usual “take care” or “good luck” but in the same tone.
