How to read a trend report critically
A trend report that survives critical reading earns its place; one that does not get filed with a one-line summary of why it was set aside. The critical reading is a checklist applied in order, and each step takes a few minutes. A report that passes all the steps is a useful input; a report that fails at step one or two is set aside without ceremony.
Step one is authorship. Who wrote the report, and what is their relationship to the industry? A report by a trade body that funds itself through member subscriptions has different incentives from a report by a supplier-funded content-marketing team, and a report by an academic researcher has different incentives again. The author is the largest single source of bias in the document, and the buyer should know who the author is before reading the claims.
Step two is methodology. Where did the data come from? A report that surveys a panel of named respondents with a stated sample size is in a different category from one that aggregates supplier submissions or counts social posts. A report that draws on customs shipment data with a stated scope is in a different category from one that cites "industry insights" without explanation. The methodology section is the section a buyer should read twice; if it is missing, the buyer should treat the rest of the report with caution.
Step three is consistency across years. A figure that appears in three consecutive reports, repeated verbatim, with no source attribution across the years, is borrowed text rather than re-measured data. The same applies to a palette that recurs across years with no movement, or to a forecast that recurs as an "established" trend year after year. The buyer should note claims that recur verbatim and treat them as one claim, not three.
Step four is the comparison the report makes. A trend report that compares a statistic to last year’s statistic and shows growth is reporting a year-on-year change; a trend report that compares a statistic to a five-year-old statistic and shows growth is reporting a different kind of change. A useful read is to check the comparison period. Where the report compares to a comparison period that is not stated, the figure should be treated as decoration rather than as evidence.
Step five is the recommendation. A report that ends with specific recommendations that favour a particular product category, decoration method or supplier type is editorially biased by design. Recommendations are useful for suggesting where the report author thinks the industry is going; they are not useful as evidence that the industry is going there. A buyer should treat recommendations as the author’s stated view, weighted by the author’s incentive, and discount accordingly.
Step six is the action. A report that suggests a buyer change the catalogue in a particular direction should be tested against the brand strategy and the audience before being applied. The test is not whether the suggestion is true; the test is whether the suggestion, even if true, requires a buyer change in this cycle. Most report suggestions do not, and the buyer is allowed to file them for the next cycle.
