It works when the same class of decision recurs often enough to build a track record. It works when the team already knows and airs each other's strengths and weaknesses, and when the decision matters enough to justify the overhead. Dalio's own version at Bridgewater ran on years of data about what each person was like.
It fails when nobody has a real track record. That is most early-stage startup decisions. With no history, believability collapses into seniority or confidence. You have rebuilt autocracy with extra steps. It also fails when the team scores in public without trust already in place. That reads as ranking people rather than ranking opinions. And Dalio is candid that the cultural cost is real. He says outsiders often saw the transparency at Bridgewater as a cult.
Where operators split. Dalio's whole approach assumes decisions improve when you turn judgment into data. Jason Fried argues close to the opposite for product calls. He says people are feeling creatures at heart. The feel of a thing often outweighs the spreadsheet. Both are describing real conditions. Dalio is talking about decisions that are repeatable, high-stakes and evidence-rich. Fried is talking about taste, where the track record you need does not exist yet.
