Online dating, how many of us lie about our profiles to change the psychology of someone’s perception about us? Do we really say what we think? How do we measure one’s mind? Joel Pearson talks about the ways and techniques scientists and psychologists can hack into our brains. Through techniques such as visual illusions and emotional inception, we learn about how malleable our brains can be and the means in which we can measure it.
