“Intense intuitive concern may be overruled (but not reduced) by less intense concerns resulting from conscious consideration.”
From The privacy paradox – investigating discrepancies between expressed privacy concerns and actual online behavior – a systematic literature review (2017) · cites this paper as Kahneman, 2003
In the citing paper
“there are two explanations for the privacy paradox: Either individuals act on their intuitive concern without assessing the risks due to incomplete understanding of it (no considered concern takes place) or high considered concern may be overridden by low considered concern”
From The privacy paradox – investigating discrepancies between expressed privacy concerns and actual online behavior – a systematic literature review (2017) · cites this paper as Kahneman, 2003
In the citing paper
“System I is fast and automatic but is vulnerable to influences that inhibit the rational decision-making process (produces intuitive concern for instance), whereas System II is rational and responsible for reasoning (produces considered concern, for instance).”
From The privacy paradox – investigating discrepancies between expressed privacy concerns and actual online behavior – a systematic literature review (2017) · cites this paper as Kahneman, 2003
In the citing paper
“But people actually lack access to their own associative machinery 18,19 , and rely on heuristics to understand the decision-making of other people 20 .”
From Understanding, explaining, and utilizing medical artificial intelligence (2021) · cites this paper as [18]
In the citing paper
“Second, we focus on economic rationality as defined by revealed preference analysis, whereas rationality is often defined more broadly in the literature to include various decision rules and heuristics (40, 77, 78).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
