dc:description "Downloaded dataset_pollen_raw.csv, hashed it, and kept rows with species hb. A load is the combination of period, day, site and bee. Morphotype shares in a load were summed. A morphotype counts toward the verdict when its share is at least 5% of counted grains. The pre-registered rule was applied to the proportion of loads with two or more such morphotypes. Bumble-bee rows were not scored.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 0.107824 proportion of honey-bee pollen loads with two or more morphotypes each at least 5% of counted grains (n = 1048, exact proportion of loads; grain counts are the dataset's microscopy counts). Interpretation: The claim is about the honey bee on one expedition, not about bumble bees and not about colony-level honey. A corbicular pollen sac is the pollen the bee carried back from a trip. The Dryad dictionary says a sac with more than one pollen morphotype has more than one row, and that bee numbers do not correspond across days, so the load key includes period, day, site and bee. Bumble-bee rows (bb) are ignored. A 5% grain floor is the pre-registered allowance for stray grains; it is not in Aristotle.";

A refutation that rests on a very small proportion of loads is weaker than one that rests on a common mixture, and the confidence rule is fixed in the analysis: 0.80 if p >= 0.05, 0.45 if 0 < p < 0.05, 0.40 if p = 0 (one landscape cannot establish a universal never).",

The claim is refuted if n >= 30 and p > 0, because Aristotle says the bee never meddles with another flower until it has returned to the hive.

If the CSV cannot be fetched or lacks the columns species, period, day, site, bee, morphotype and either prop or both count and total_count, the verdict is inconclusive with reason data-unavailable. The proportion of loads with two or more morphotypes at any abundance, with no 5% floor, is reported and is not used for the verdict.";
