A simple sign someone’s an ISTP 🦉🧙🏻♂️🔮 Here is a simple sign someone is an ISTP Now… While this is a simple sign I wouldn’t recommend it as it might make them grumpy and not like you. If you already suspect they are an ISTP because they are tinkering with things and talking logically. Ask them how they feel about the idea. You will see their face kind of reset and go blank for a second then reload and give a grumpy response. #wizard #istp #istppersonality #16personalities #personalitytype #philosophy #psychology #selfimprovement #carljung
