Does this sound like the set of challenges you might be facing?

• The case feels solid because I’ve got several decent reasons stacked up, but I keep ignoring that the whole thing actually hinges on one shaky step I’ve never checked
• I’m betting on "this will happen and then that will follow," and the link between them feels airtight to me
• I traced a problem down to what felt like the real cause and it all hangs together so neatly that I trust it completely
• When two things fit together neatly in my head, I treat the whole package as more likely than either piece alone
• I let all my looser acquaintances go totally silent because they felt less important than my close people

Practices that may help

1. Rate the strength of each logical link
   Assign a confidence to each "supports" or "rebuts" link, not just to the conclusion.
   Argument Mapping
2. Red-team joint scenarios before betting on them
   Before acting on a conjunction ("X will happen AND Y will follow"), assign a skeptic to attack the "and."

3. The Strength of Weak Ties
   Sociologist Mark Granovetter found that weak ties — casual acquaintances rather than close friends — are disproportionately valuable for finding jobs, opportunities, and novel information, because they bridge social clusters you wouldn’t otherwise reach. The effect is well supported observationally and has held up across multiple replication attempts.
4. Verify the root cause by tracing back up the chain
   After reaching a root, work back up: does each "because" in the chain make logical sense?

5. Test each component probability separately
   Before judging a joint claim, estimate each element on its own, then check whether the conjunction is lower.

6. Maintain weak ties for information and opportunity
   The 50-to-150 layer isn't maintenance overhead — it's your network's reach.

7. Apply the same evidence standard regardless of whether you like the conclusion
   Grade the evidence before you know which conclusion it supports.
   Motivated Reasoning
8. Count the assumptions each explanation requires
   When two explanations fit the facts, count how many unverified assumptions each one rests on.

9. Surface and test underlying assumptions
   Identify the implicit assumptions that your reasoning depends on and test whether they hold.

10. Surface the hidden premises
    Find the unstated assumptions that the argument needs to work.
