What is expertise? How do we know someone is an expert?

Expertise is observable accomplishment or skill in a specific field. An expert is someone we can trust to tell us the facts we need to know. Expertise means proficient at a skill. An expert can do something better than almost anyone else.

For example: LibrarySpot.com is described as a place where you can access reference books (dictionaries, encyclopedias, journals, etc.) and the experts who write them. Thus people with expertise are those who write the information we view as evidence, peer-reviewed, accepted as true.

Another example: We know David Weil is an expert on economics because he teaches at Brown University and publishes works that are verifiable. Other experts refer to him. Other experts support the things he says.

Why should we check an expert's view?

  • Seeking multiple sources for information (sometimes called triangulation) is a dependable way to get the whole story and not just part of the story. Triangulating at least three solid sources of information is particularly important if the subject is a complex one.
  • Experts have time to do more research than you can accomplish. Take advantage of their work; let them search for you.
  • Try to find two experts with totally different opinions. If you can, then you must do some thinking. If you can not, then your decision will be easy.
  • Citing an expert adds credibility to your work.

How can I find people with expertise in my subject?

  • Search for authors who have written about your topic and contact them via email. It is sometimes possible to query an expert's name with the keyword EMAIL and find an active email address. If you can find a bio or vita page about the expert, there may be an email link there. This probably won't work if they are also a celebrity.
  • Go through an online network such as LinkedIn. Search for the name and see if you have any close connections who can help you make a connection.
  • Ask your librarian or teacher or someone else you know who is interested in the topic.
  • Online libraries are offering reference librarian services virtually. These ask-the-librarian services work quite well.
  • Search for Ask-the-expert services.
  • There are many who swear that newsgroup and listserv connections give them the answer to any question they ask
  • Avoid asking questions on unsupervised online forums unless you can tell truth from fiction. It's impossible to tell who's an expert and who's not. Plus, many 'experts' in forms don't use real names, making it hard to cite them as a reference.

Let's Try It!

Pick a topic of your own. Find a web page or service that allows you to ask an expert a question. Your question may already be answered by an FAQ (Frequently Asked Questions) the expert supplies. Or the expert may respond to you directly.

When expertise comes directly from the author who conducted the research it is called a primary source of information.
