Attitude means everything in Deus Ex: Mankind Divided. Certain situations go beyond mere chit-chat and land you in character debates. Each debate weighs heavily on your game's outcome, and not every answer leads to success. Learning how to give the best answers does, guaranteed.
Like most aspects of Deus Ex games, the key to become a master of debate lies in using the right augmentation. Specifically, an augmentation called the Social Enhancer lets you scan your debate opponent's mental state and pick out the best answer at each juncture. Social Enhancer also lets you interrupt and persuade opponents.
Armed with Social Enhancer, enter into a debate and keep your eye on your opponent's Alpha, Beta, and Omega bar on the top-left side of the screen. Those boxes will flash during the conversation. The box that flashes the most is connected to the answer you need to give.
Remember to watch for opportunities to interrupt or persuade during debates. Both techniques work well when conversations aren't going your way, or when you want to move conversations along quickly to an outcome. You'll know when to persuade or interrupt by an on-screen prompt. Prompts don't stick around for long, so be ready to act.
