In my experience the data presented here shows the need to cut further or obtain additional data. There's some correlation, but the data appears to be a rough aggregate and the absolute magnitude of the movement is small. Also unclear if cyclical or macro effects were removed. Pretty much all the other comments here are anecdotal or attempted to draw conclusions from insufficient data. This is why pop psychology is generally reviled by psychologists.
