Of course you will still need to trust others to reproduce results in areas with which you are unfamiliar, but this is still better than implicitly trusting peer reviewers.
Same thing with software security: if software is open source then I still need to trust someone else to determine if the source code is malicious, but it is better than implicitly trusting software because e.g. “a contractor has done a security audit.”
Basically I don’t believe you can truly trust closed-anything, especially scientific analysis. You need _less_ trust when the thing is reproducible, which is the best you can ask for.
