It has been a bit crazy so far. But I've been told only the first 100 years or so will be like that.

Brain is a computation device. So given the same input one expects to see the same output.
But stress or even just being watched makes us act differently and perform differently.
One way to think about it, is to say, Obviously these change the “inputs” or at least the global variables / environment in which we do computation. So no big deal, when we figure out who brain does task A, then we’ll understand how stress affects our performance in task A.
But it might also be the case that stress may change the hardware or generally speaking the computational resources available for a task. Like it may add noise? or increase sensitivity or generally change the setting of the system.
Although we have a lot to learn about brain, the assumption of brain being a digital computer (or maybe even a turing machine) needs more thought. Or maybe my brain is under too much stress right now …
