Roger McNamee is a author musician and investor
True
Accuracy: True. True. Authoritative biographical sources directly describe Roger McNamee as all three: Penguin says he has been a Silicon Valley investor for 35 years and “plays bass and guitar” and “is the author” of named books; Harvard likewise details his investment career, says he “is the author,” and that he performs in bands. An older Cooper Hewitt interview is consistent historical context. No supplied passage contradicts any part of the claim. Verdict confidence: 97/100. The core claim is directly supported by multiple verified passages that explicitly identify Roger McNamee as all three: an investor, an author, and a musician. S1P1 states he "has been a Silicon Valley investor for 35 years," "plays bass and guitar in the bands Moonalice and Doobie Decibel System," and "is the author of" named books. S3P1-S3P3 independently reinforce the same three roles, including his investment career, authorship, and regular concert performances. This directly resolves the full assertion with little ambiguity. The only minor limitation is that these are biographical summaries rather than formal occupational definitions, but for this broad descriptive claim that does not materially undermine the verdict. Method: verdict-evidence-v1. Not a calibrated probability.
