Using this argument, you can basically discard any kind of inference on any large system. That’s not particularly convincing. It’s not because something is complex that you can’t a posteriori conjecture links between causes and consequences at a macro level. What economic journalists and analysts mean when they say a move with triggered by something is that both events happened in a time frame which is conductive to saying a correlation exists. Turn out that Google published is earning Tuesday with larger than expected capital expenditure and little return to show for it and then the market tanked. That’s what they mean by reason and that’s how everyone understands it. We know the market is large and made by a lot of actors. We are not dumb. You are free to think it’s all random happenstance. I’m free to think you have an axe to grind and prefer denial to rational thoughts.
