Abstract
Benbasat and Barki (2007) argue that TAM has been both a blessing and curse for the IS field and they detail reasons why this is the case. Our response to their critique is to highlight areas of agreement, disagree with one of their assertions, and extend their thinking along another, related line. Specifically, we agree that some TAM constructs, namely perceived usefulness and system usage, need to be more closely examined in order to break up the "black box" portrayal of these concepts. Our view of Benbasat and Barki's characterization of TAM as unassailable is that common methods bias has never been well tested and that TAM linkages may in fact be methodological artifacts. Finally, it is argued that the field desperately needs more parsimony in TAM models and that meta-analysis is one good way of achieving this goal.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
