Credence Goods
Credence goods are products consumers cannot verify quality or outcomes even after purchase, often requiring professional advice because the seller knows much more than the buyer.
Credence goods are a specific type of economic product where consumers lack the information or expertise to assess quality, let alone outcomes, even after purchase. Unlike experience goods that can be judged by use, credence goods often require professional advice or third-party verification because the consumer cannot tell if the service was necessary or effective. The concept highlights chronic asymmetric information problems in markets where producers know vastly more about the product than buyers do.
What this means in real life
When you take your car to a mechanic who says you need a new transmission, you can't easily verify whether that's truly necessary or if a cheaper repair would work—you must trust their professional judgment.
What it isn’t
Not the same as 'experience goods,' which you can judge after using them (like a restaurant meal). Credence goods remain hard to evaluate even after consumption because you lack the expertise to know if the seller's claim was justified.
Commonly misused online
People often use 'credence goods' to mean any product you can't inspect before buying, but the key is that expertise or trust remains necessary *even after* purchase—not just before.
