I have this same predilection and I have thought a lot about it and I am pretty confident I know where this comes from for me: When I was young, after opening my first checking account, I fat-fingered a transfer from checking to savings online and the bank software interpreted this as me trying to transfer more than I had, so it happily proceeded to give me a large cash advance and then charge me $75 for the trouble, and another $35 for the NSF fee. Now, maybe because I work in software, and maybe even moreso because I have literally written checking account software - I do not use online or mobile apps for non-trivial banking things. I call a person. Or I walk up to a person. I verify everything they are doing before they do it, and by acting as my agent during more complicated tasks they assume liability if they fat-finger something or mess something up (so far). For the curious: the online form had separate inputs for dollars and cents, and some JS regex removed punctuation marks. So when I typed "1,0,period, 0, 0", instead of trying to transfer $10, it transferred $1000. I absolutely breezed through the "verify the amount step".
