Little useless-useful R functions – Absurd bias DAG with useless mental shortcuts
Exploring graphs is always a fun. Attaching the edges and nodes with real examples of psychological effects and accompany them with useless mental shortcuts is beyond fun. This is why we will call it a “cognitive bias” explorer using DAG.…
