> Several handbooks on highly effective communication in organizations are:
1. “Winning” by Jack Welch and Suzy Welch, which emphasizes clear communication, open dialogue, and transparency in organizational success.
2. “Fierce Conversations” by Susan Scott, focusing on transforming everyday conversations at work to achieve success.
3. “Radical Candor” by Kim Scott, which promotes empathetic yet direct communication in professional settings.
In your reading of those titles and summaries, do they seem likely to recommend communicating layers of fluff to executives?
Scroll down to the 2nd question: "What advice do these books offer to a subordinate who wants to give feedback to their manager? What's their reasoning for the advice?"
LLM(and LLM+) afaik, even Perplexity, do not do textual analysis. They do not “know” what is in the book, they will only try to predict how someone else would answer your question based on data in the training set. If there are not many similar questions asked and answered accurately, the results will be poor.
