Prediction text
NASA will imminently find >90% probability evidence of microbial life on Mars | NASA administrator said that he predicted more than 90% plus probability that NASA will eminently find evidence of microbial life in some form on Mars
Verbatim quote
NASA administrator said that he predicted more than 90% plus probability that NASA will eminently find evidence of microbial life in some form on Mars
Predictor: Jared Isaacman (NASA administrator)
Evidence about this node from Jared Isaacman (NASA administrator) is multiplied by κ in /api/intake. Lower κ = less weight; floors at 0.10 (effectively silenced) and caps at 1.00 (full weight).
Reference class
This node isn't linked to a reference class. The Bayesian update applies without outside-view blending.
