Abstract

fetched live from OpenAlex

HE observation by Fox (1931) that phenylthiourea (phenylthio-T carbamide) was tasteless to some persons while most people tasted the compound as bitter was followed by a genetic analysis by BLAKESLEE and SALMON (1931). Their findings suggested an autosomal recessive mode of inheritance for taste blindness to P. T. C. BLAKESLEE (1932) observed that some persons described the taste of P. T. C. by some term other than bitter, including sour and sweet. RICHTER and CLISBY (1941) reported that among 261 persons 15 (5.75 %) described subliminal solutions of P. T. C. as sweet. Likewise HARRIS and KALMUS (1949) remarked that some persons cha;*acterized P. T. C. as sweet, sour, salty, for example; this particularly so near the taste thresholds of these persons. Examining Japaneses with P. T. C. powder CHIKAUCHI (1952) noted that a few persons found the taste sweet or salty. LUGG (1955) found 3 Malayan Negritos to describe weak solutions of P. T. C. as sour; one of these persons tasted solution 14 (HARRIS' and KALMUS' denomination, 1949) as sweet. In their research series LUGG and WHYTE (1955) noted, among other exceptional taste qualities for P. T. C., sweet taste for this substance in 0 to 2 per cent of the Europeans and Asians. Of 50 Senois in Malaya 8 per cent tasted P. T. C. as sweet at or close to their taste threshold (LUGG 1957).

Full frame distilled prediction

Teacher imitation

Not 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.
