Summarize the following:
One of the worst things you can do when dealing with people who are less intelligent than you is to let them know that you think they are stupid. This will only make them angry, which means they will not be listening to you. If you want to communicate effectively with people, never tell them you think they are stupid (or insult them in any other way). If you get frustrated with someone who just doesn't seem to understand something, try asking them what you can do to help them understand, instead of insulting them for their lack of abilities. For example, you could say, "I see you're struggling to understand this math problem. How can I help?" Everyone is good at something, so try to hone in on other people's talents. A person may be less intelligent than you, but have better people skills or be a faster typist. Recognizing that all of these skills are important and valuable will help you appreciate others more. Encourage the person by pointing out their strengths and complimenting them, even if they are struggling with other things. For example, you could say, "I know you're having a hard time getting used to the computer system, but you did a great job interacting with the customers today." No matter what you think of other people, you should always treat them as you would want to be treated. Being kind and respectful, regardless of how you feel about someone, will make it much easier to get along.  If you're having trouble being empathetic, take a moment to try to see the world through the other person's eyes. This may help you recognize their unique talents and appreciate how hard it is to deal with people who are more intelligent. Don't start arguments, even if you truly believe the other person is wrong. This will most likely be futile and will just frustrate you. If you feel the need to express your point of view, consider saying something like, "I think ________, but your idea is interesting too," instead of, "You're wrong. The right way to do this is ________." Sometimes it's best not to say anything about another person's lack of intelligence, even if you are forced to work with them. Be sure to carefully consider whether reporting the situation will benefit you in any way.  If you work with the person, be sure to think about how your boss might react to your comments before you report them. If you determine that any negative reaction is worth the risk, be sure to approach the situation by talking about specific facts, rather than your own opinions of the person. If you go to the school with the person and have to work with him on a project, treat the conversation with your teacher the same way you would if you were an employee talking to your boss — stick to the facts. You could say something like, "I noticed that X is having a lot of trouble operating the computer system, and it's really slowing down the team. The team completes 15 tasks on average while X completes only six or seven. I think they could benefit from more training, or possibly being assigned to a different task."

Summary:
Don't call the person out. Look for their strengths. Be empathetic. Think carefully before reporting them at a workplace.
