What Is Visibility Bias in Cannabis Market Reports?

The Thailand Cannabis Report  ·  2026 Edition  ·  Field-verified market intelligence  ยท  Last reviewed: 2026

Visibility bias is measuring only what is convenient, registered, and reported, and letting that convenient half quietly become the definition of the whole market.

There is a bias running through nearly every report written on this market, and it is worth naming, because once you see it you cannot unsee it.

Why Do Analysts Measure Only What Is Easy to Measure?

Analysts naturally gravitate to what is convenient. The registered, the reported, the tidy. The licensed shops that can be counted from a database. What is convenient to measure then quietly becomes the definition of the market, and everything harder to see is assumed not to matter.

What Happens When the Hard-to-Measure Part Is Actually Most of the Market?

In this market, the part that resists easy measurement is not a rounding error. It is the larger share of the volume and the consumers. A report that measures only the convenient half is not slightly off. It is describing a different, smaller market and calling it the whole.

We went looking in the places the data does not reach, because that is where most of the real market turned out to be.
