How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to artifact is feature.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Research methods and statistics

A false finding produced by the procedure

A finding that reflects how a study was measured or designed rather than the thing being studied: an effect that shows up in the data because of the procedure, not because it is real. Orne's 1962 paper on the social psychology of the psychological experiment showed how the cues a study gives its participants, which he called demand characteristics, can manufacture results that look like genuine effects. The referent is a spurious empirical result produced by the method, unlike a physical object dug from the ground or a false mark visible on a scan.[1]

Unit
A single spurious effect or reading attributable to the procedure
Recovery means
Not applicable
Measured by
Detected by control conditions, replication, and design checks that isolate the procedure's influence from the real effect

Medical imaging

A false feature produced by the imaging process

A feature that appears in an image or recorded signal but does not correspond to anything in the object being examined: a streak, shadow, ring, or ghost created by the equipment or the reconstruction rather than by the patient's anatomy. Barrett and Keat's 2004 review Artifacts in CT: Recognition and Avoidance catalogued how scanner physics, patient motion, and reconstruction methods generate such false features, and how radiologists can tell them apart from real findings. The referent is a false mark in a picture or signal, distinct from a human-made object or a spurious result in a data analysis.[2]

Unit
A single false feature appearing in an image or signal
Recovery means
Not applicable
Measured by
Identified on the image by its pattern and location, and reduced by calibration, filtering, or corrected acquisition
