Was this really confirmed just know in psychology? At least here in Germany this is ubiquitous. "Start criticism with the positive" is taught everywhere from elementary school to university, from self-help groups to management courses. This is so normal that it is usually not attributed to Pascal, but to common-sense psychology and good social behaviour in general. I alway thought this was well-established in science for decades - not something we verified just now.
