Do You Agree? Do You Strongly Agree? The Effect of the Number of Response Categories on Response Processes and Verification of Substantive Hypotheses Abstract. This study investigates how the number and labeling of response categories in survey scales affect respondent behavior, psychometric properties,

UK researcher part of team analyzing bias in large language models The study, “The Silicon Gaze: A typology of biases and inequality in LLMs through the lens of place,” published in Platforms and Society today.

LLMs increasingly shape how people understand the world. But what if the “world” they present is systematically uneven?

New research from the @oii.ox.ac.uk, alongside colleagues at @universityofky.bsky.social, offers an answer.

Please join! We will be starting in about five minutes.

Really amazing scholars (thank you @bradytwest.bsky.social and @randridge.bsky.social !) here to provide the fundamental science for free, for everyone @um-psc.bsky.social

Everyone shaking their head or laughing at this video has been tempted to do this on multiple occasions! Be honest! 😂

Make free throws.

Get rebounds.

Michigan just getting beaten by the basics right now.

LFG.
