How will you decide if this expert is well qualified?

An expert should have training in their field of expertise. Can you find that training listed in their CV or somewhere else that is publicly available? Do they attend meetings and conferences and interact with their peers at these events? Do they have a good track record of experience in their field? Do other scientists refer to their work?

Here are some points that you should consider when you’re trying to determine who is a genuine expert in a particular field.

• Does the expert have proof of their qualifications, like university degrees or professional achievements? Be careful of experts who exploit their high profile in one area of expertise to make recommendations on issues clearly unconnected to their field. This is called epistemic trespassing.  ^{1, 2, 3, 4, 5,  6}
• Recognition from peers is a crucial indicator of expertise. Do other experts in their shared field refer to them or the impact they’ve made? Is there evidence that they engage with other experts? ⁷
• Experts who advise on policy should show awareness and sensitivity of the broader impacts of their advice. Is the expert willing to engage with the public on these issues? 8, 9
