Thanks for your reply.

To explain:

“Talk down to one intelligence” is talking to a person as if they were a child. I see this a lot in the real world. I live in China and see many foreigners talking to Chinese people as if they were children or stupid because English is not their first language.

This is highly insulting to the individual concerned.

You should rather explain in a clear, simple manner but treat the listener as an adult and talk to them on that level.

“Talking up to ones intelligence” is pretending that you understand something and talking at a higher level than you have knowledge of.

For instance, talking to a high level CEO as though you have experience in his field when your knowledge is limited to sweeping the streets.

Hope that explains things better – let me know if not.

What you are saying about product as well as buying process makes sense. However, “Language or graphics that “talk-up” or “talk-down” to my intelligence” is something that I am unable to understand quite clearly.
