I'll be honest - I'm in marketing and I still fell for the "only 3 spots left" thing last month with a mastermind group. Knew exactly what they were doing, watched myself rationalize it anyway. Ended up signing up at midnight because I was convinced the price would jump tomorrow. Here's the thing though - in this case, the scarcity was real. The group actually was limited to 10 people because of how hands-on it is. That's the difference between manipulation and genuine scarcity. These days, I use a simple rule: if the scarcity doesn't serve the product's quality or the customer's experience, it's probably BS.
