the.com/aggregation
Where a thousand small truths get blended into one confident lie called an average.
means The act of gathering many separate items, data points, or units into a single combined mass or total.
from From Latin aggregare, 'to add to the flock' — built from ad- ('to') plus grex/greg- ('flock' or 'herd'), the same root that gives us 'gregarious' and 'egregious.' The Latin verb originally meant herding stray animals back into the group, so at its root, aggregation is simply the ancient shepherd's job: rounding up scattered things and calling them one.
