At the same time, the Force hid the future in which, due to the activation of the biochips, the clones would undergo fundamental personality changes (the Bad Batch makes it quite clear that the clones behave very differently post-activation) and murder them all. This is, of course, the same mistake Palpatine makes in the OT. He trusts the Force's revelation that there's no threat on the Forest Moon and completely misses the possibility that the Ewoks would side with the Rebellion and support the attack on the bunker, which is ultimately his undoing. It's the same mistake - arrogantly trusting the Force instead of properly planning out contingencies - from the opposite side.

Ironically, given Lucas' stated goals to increase spirituality via Star Wars, both trilogies hold the same lesson: don't trust mystical insight over hard evidence and sound preparation.
I wonder how much of it is trusting the Force too much and how much of it is seeing what you want to see, interpreting things in such a way as to support your own interpretation as it were.

Take Anakin for example. He's the Chosen One, the one who will bring balance to the Force. Except the Jedi Council doesn't actually want the Chosen One to show up because they believe the Force is already in balance and has been ever since they destroyed the Sith a thousand years ago. Anakin's arrival isn't just unwelcome, it's terrifying. If the Force has deemed it necessary to bring forth the Chosen One, how badly out of balance has the Force become and why did the Jedi not see it? That's why they don't believe the prophecy is real, or that it could have been misinterpreted.

They allow their own bias to cloud their judgement and you could certainly argue it colours their attitude towards Anakin as well. It's hardly a secret that Mace Windu held no small amount of animosity towards Anakin and The Clone Wars and a fair bit of supplemental material are pretty explicit that he's someone who cares very much about how the galaxy perceives the Jedi Order and Anakin's existence as the Chosen One is practically an admission of guilt that the Jedi Order hasn't done its job.

Then of course there's the whole "bring balance to the Force" thing itself. The Jedi Council just assumes that the natural state of the Force is their side being the only one that exists, so naturally they assume bringing balance to the Force means destroying the Sith. I believe the Sith assumed the opposite, that the Jedi perverted the nature of the Force and that the Chosen One would destroy them. Ultimately both were wrong, oblivious to the truth that the Chosen One existed to leave the galaxy behind and remain on Mortis where he would keep the light and the dark in balance, but that's kind of the point right? When you think you're in the right, you twist the facts to support your own position. Both the Jedi and the Sith assumed the Chosen One existed to benefit them and because of their machinations he destroyed them both.
