Three dominant themes in the discussion

Theme Summary Representative Quote
1️⃣ Exams should assess only material that was actually taught; unsolvable or unexpected questions cause frustration and are poor measures of ability. Users argue that testing on undisclosed concepts undermines the purpose of assessment and that alternative formats (e.g., homework) are more appropriate. “As a teacher, I can tell you that students get really angry if you put a question on an exam that requires a concept not explicitly covered in class.” — vlovich123
2️⃣ The tension between “thinkism” (over‑theorizing) and “doism” / hands‑on problem‑solving; both academic rigor and practical doing are needed for real‑world competence. Commenters stress that learning through building, debugging, and iterating is essential, and that blind theoretical exercises can be counter‑productive. “I call this, the way to learn stuff is by doin' stuff. Also buildin' stuff! (Which is the best type of doin’.)” — andai
3️⃣ Misconceptions about managerial competence; many bosses possess niche expertise that employees overlook, and assuming they’re “clueless” can stem from a lack of context. Several replies share anecdotes showing managers often know specific, vital details (e.g., accounting rules, grant deadlines) that employees didn’t previously appreciate. “I realized as my eyes glazed over… damn this is just the same reaction people who don’t understand browser rendering engines get when I start telling them about different events.” — bryanrasmussen

These three points capture the core conversation: the limits of traditional exam design, the value of experiential learning versus pure theory, and the nuanced reality of workplace expertise.
