The modern American woman of reproductive age is extremely vulnerable to Tarot cold reading. Here's why:

Narcissism: Generation Y was raised in a culture, where self esteem was regarded as the highest ideal. Children were coddled and told that they were special snowflakes who will always be loved. These children grew up to become narcissistic adults who love to talk and hear about things about themselves. At its heart Tarot is about looking at pretty pictures and talking to people about themselves, so you can see the appeal.

Spiritual but not Religious: Religion isn't at the heart of american culture anymore. Most of Generation Y had some religious instruction in their early years but really not enough to keep them secure in their faith. Most Christians iv run into sang songs about God in their youth but were never taught the dogma at the heart of their religion. This leaves people Spiritual, vulnerable to the suggestion of divine forces but not devout enough to reject paganism or the occult on dogmatic grounds. Atheism and Nihilism, the logical successor to religion is hard for women to fully swallow because women don't deal with chance and risk very well. Woman need morality because the enjoy the security of living their lives by rules. A logical atheist would quickly reject the stupidity of tarot but the agnostic will generally be open to the idea.

Sheltered from Criticism: Modern women don't respond to criticism very well. Right now there is some 32 Body Mass Index hefer yelling im not chubby im curvy at her boyfriend and subsequently typing angrily into the internet. Tarot allows you to say harsh things with plausible deniability. If done right this jarring reality slap will be interpreted as a beneficial spiritual experience. The Devil represents addiction and vice. The Man and Woman have loose chains around their necks. They are free to leave but choose not to even though staying brings them harm. Do you have any addiction in your life Fat Susan?

Addiction to Novelty: Consumerism can't exist without an addiction to novelty. People are conditioned to love the new and throw away the old because doing so fuels demand. Years of commercials have instilled consumerism in american minds and the economy is chugging along because of it. Many women will be drawn to getting a tarot reading simply because they never had a tarot reading.

Believes in Fate: When the modern American Women is called out for an amoral act ex: cheating on her boyfriend, abandoning her friends at a party to suck a dick, she will vehemently deny agency. I don't know it just kinda happened. According to women they do not perform amoral acts, amoral acts happen to them. Belief in fate is a powerful defense mechanism against culpability. By doing a cold reading and talking about fate you will reassure a woman that she is not completely responsible for her actions. This will defiantly create good woman feels.

Why should a rational male like myself get involved in stupidity?
