Abstract
This article explores the (in)ability of automated tools to measure the deliberative quality of online user comments along the standards set out by Habermas: interactivity, diversity, rationality, and (in)civility. Utilizing a stratified sample of manually coded comments (n = 3,862) responding to news videos on YouTube and Twitter, we examined the performance of rule-based measures (i.e. dictionaries), machine-learning classifiers (conventional and transformer-based) and measurements by generative AI (Llama 3.1, GPT-4o, GPT-4T). We present results for over 50 metrics side-by-side to judge the opportunity costs of choosing one method over another. The results revealed strong variation across different groups of models. Overall, our expectation that more modern methods (transformers and generative AI) outperform the older, simpler ones was confirmed. However, the absolute differences between these model groups strongly depended on the measured concept, and we observed strong variance in performance among models of the same group. We provide recommendations for future research that balance ease of use with the performance of automated measurements, along with important cautions to consider.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
