q2 · i? · causal · r2

Multinomial logistic regression over plain-persona assignments (Table 2) shows "Nigerian names are more likely to be assigned toQuality Assurance team" and South Korean names more likely for Interface Design; the article reports significant odds ratios but this quote prints no single effect-size value, so no magnitude is asserted.

"compared to Chinese names (as the reference nationality), Nigerian names are more likely to be assigned toQuality Assurance team; South Korean names are more likely to be assigned to the Interface Designteam and less likely to be assigned toDatabase team."
