If you make her feel a positive emotion like laughter is that what attraction is for her?

attraction is created by fascination. not gimmicks, magic tricks or routines.
these all play a role in creating fascination. a positive emotion is just what it is, a positive emotion. attraction can't really be defined by an emotion.

but remember the rule: leave her better off than you found her. so yes laughter is one of the qualities of fascination. so is a "oooo and ahhh". as well as a provoking though. attraction comes 'n goes though. the important part is hooking her in and getting her to invest herself in you emotionally. then there will be no buyer's remorse later on when you f-close. rapport is the best way to do this.

No. When women go to a comedy show they don't think "Gosh I wanna fuck that guy" after they laugh at his jokes.

A dancing monkey can make them laugh, but it doesn't mean they're attracted to monkeys.

Laughter is simply one tool to get women to buy into your frame. However, you have to have the attractive sexual frame in the first place to get the attraction going.

Attraction is created from tension, inequality. That's why Mystery has his whole neg theory and DHV thing to lower her value and raise yours. Attraction is DESIRE. She desires to achieve your level in Mystery Method. That's just one example. Every method has a similar dynamic to create attraction.

Another example is creating sexual state. You create the mood so that there is sexual desire but it isn't verbalized, it's controlled. The inconsistency between what is felt and what is said created tension and therefore attraction.
