We were going to find that elections were manipulated wildly and regularly. Yet there was never any proof that that happened anywhere in America.

It's great proof of IBM's innovation.

This isn't proof that they were used, but a likely suggestion. They were present in abundance at the dawn of time and could have been useful in creating the first life form.

I do not think there is a demonstrative proof (like Euclid) of Christianity, nor of the existence of matter, nor of the good will and honesty of my best and oldest friends. I think all three are (except perhaps the second) far more probable than the alternatives. The case for Christianity in general is well given by Chesterton…As to why God doesn't make it demonstratively clear; are we sure that He is even interested in the kind of Theism which would be a compelled logical assent to a conclusive argument? Are we interested in it in personal matters? I demand from my friend trust in my good faith which is certain without demonstrative proof. It wouldn't be confidence at all if he waited for rigorous proof. Hang it all, the very fairy-tales embody the truth. Othello believed in Desdemona's innocence when it was proved: but that was too late. Lear believed in Cordelia's love when it was proved: but that was too late. 'His praise is lost who stays till all commend.' The magnanimity, the generosity which will trust on a reasonable probability, is required of us. But supposing one believed and was wrong after all? Why, then you would have paid the universe a compliment it doesn't deserve. Your error would even so be more interesting and important than the reality. And yet how could that be? How could an idiotic universe have produced creatures whose mere dreams are so much stronger, better, subtler than itself?

We need no elaborate statistical proof that trade depends on prosperity in the industrial countries.

Like every thoughtful parent in every age of history, Neil consoled himself, "My generation failed, but this new one is going to change the entire world, and go piously to the polls even on rainy election-days, and never drink more than one cocktail, and end all war.
