Meeting dynamics

I just stepped out of a meeting at the office today and I noticed how people put others down......it goes something like this....

If you ever want to put someone down and and categorize them as an uncouth peasant, just choose one of the following statements:

[After 20 minutes of detailed discussions]........

Person A says: "I think we need to step back and look at the big picture" (The implication here is that everybody has their nose so close to the detail they cannot see significant trends)

Person B retorts: "I agree somewhat, but we need to step back even further and understand the wider context"

Person C joins the fray (not wishing to be outdone): "Actually we need to get back to the core basics and go back to the beginning"

Finally, Person D chimes in with their own unique twist: "We need to approach from the bottom up, as top down approaches are now redundant".
