You can use Six Thinking Hats in meetings or on your own. In meetings, it has the benefit of preventing any confrontation that may happen when people with different thinking styles discuss a problem, because every perspective is valid.
Each “Thinking Hat” is a different style of thinking. These are explained below:
White Hat: with this thinking hat, you focus on the available data. Look at the information that you have, analyze past trends, and see what you can learn from it. Look for gaps in your knowledge, and try to either fill them or take account of them.
Red Hat: “wearing” the Red Hat, you look at problems using your intuition, gut reaction, and emotion. Also, think how others could react emotionally. Try to understand the responses of people who do not fully know your reasoning.
Black Hat: using Black Hat thinking, look at a decision’s potentially negative outcomes. Look at it cautiously and defensively. Try to see why it might not work. This is important because it highlights the weak points in a plan. It allows you to eliminate them, alter them, or prepare contingency plans to counter them.
Black Hat thinking helps to make your plans “tougher” and more resilient. It can also help you to spot fatal flaws and risks before you embark on a course of action. It’s one of the real benefits of this model, as many successful people get so used to thinking positively that they often cannot see problems in advance. This leaves them under-prepared for difficulties.
Yellow Hat: this hat helps you to think positively. It is the optimistic viewpoint that helps you to see all the benefits of the decision and the value in it. Yellow Hat thinking helps you to keep going when everything looks gloomy and difficult.
Green Hat: the Green Hat represents creativity. This is where you develop creative solutions to a problem. It is a freewheeling way of thinking, in which there is little criticism of ideas. (You can explore a range of creativity tools to help you.)
Blue Hat: this hat represents process control.
A variant of this technique is to look at problems from the point of view of different professionals (for example, doctors, architects or sales directors) or different customers.
