    "reasoning": "I have comprehensive survival analysis across multiple dimensions (gender, class, family size, fare, age). To identify the most counterintuitive finding, I need to look for patterns that violate common expectations. One pattern that stands out is the large family survival rate being dramatically lower than small families or solo travelers. Let me examine this more closely by looking at the actual family size distribution and survival rates in finer detail to see if there's a threshold effect.",
