Why does verification have a barrier to entry?

Verification is a resource-intensive job with real scale and technical barriers. The IDAEO Verification Model is built on big data from Japan, Taiwan, and Hong Kong accumulated over the long term. It requires cross-checking Official Source, First-Party Source, and Third-Party Source data, continuous checking, and re-verification on expiry. Every conclusion must have supporting evidence. If conclusions change to suit the client, they violate the Law of Independent Verification.
