Same goes for presentations.

All meetings I have been in for the last 15 - 20 years starts with "This is a high-level view". Which means "I am to lazy to analyze details". Spreadsheets and presentations feed in into this.

When I start showing details, people "turn off", no wonder many projects fail. When I started out in IT, almost all meetings were to examine details and people would work to tweak the resolution to make it better.

Spreadsheets like 123 started becoming mainstream in the late 80s, then slow slide to "High Level" started. Then the trend greatly accelerated when presentation software became mainstream. Before that, it was easier to talk details then to create a slide deck for an overhead viewer.
