Some months ago I came across some cool psychological concepts from the book "Influence : The psychological persuasion" by doctor Robert Cialdini.

Ive used some of these at interviews and at work in general. Can confirm they do work (most of the time at least.)

1. Mirroring: You've probably heard of this, but it's crazy how powerful it can be. By subtly copying someone's body language, gestures, and tone of voice, you can build a sense of rapport and connection, making them feel more at ease with you.

2. The Zeigarnik Effect: To make something stick in someone's memory, provide incomplete information or leave a task unfinished. They'll have a stronger urge to complete it and remember it better.

3. The Contrast Principle: Next time you're presenting options, try placing a less desirable one before your preferred choice. Your desired outcome will look even better by comparison!

4. Anchoring Effect: When negotiating or stating a price, start high to anchor their perception, so lower prices appear more reasonable and favorable. This ones more for HR's.

5. Foot in the Door Technique: Start by asking for something small, and once they agree, follow up with something bigger. People tend to be more open to larger requests after agreeing to a smaller one first. Take note if you're planning on raising capital lol.

6. Ben Franklin Effect: By asking for a small favor or advice, you create a sense of investment and liking in the other person. They'll convince themselves they must like you if they've helped you out.

7. Halo Effect: If someone has one positive attribute, people assume they have other admirable traits too. Keep this in mind when making a first impression. If you're good looking someone might assume you are intelligent as well.

8. Primacy and Recency Effect: Next time you're giving a presentation, place key points at both the beginning and end. People will remember them most accurately compared to the middle material. I've found this one to be very helpful in interviews.

9. Scarcity : Highlight the limited availability of something to increase its perceived value and desirability. We're hardwired to want things that are rare or in short supply!

10. Framing: How you present your information matters. Framing it in a positive or negative light can lead to drastically different responses.
