Final answer:
When ordering the problems in international business negotiations from least to most serious, values may be considered less severe than nonverbal behaviors, which are less serious than thinking and decision-making processes, with language potentially being the most serious barrier.
Step-by-step explanation:
The task of ordering various problems in international business negotiations in terms of their severity can be subjective; however, typically, the language barrier is considered the most serious issue, followed by differences in thinking and decision-making processes. Nonverbal behavior nuances come next, with differences in values potentially being the least severe, though still significant. Here is a potential order from least to most serious:
- Values
- Nonverbal behaviors
- Thinking and decision-making processes
- Language
It's important to note that the order of these issues can vary depending on the specific contexts of the negotiations and the parties involved. Values can influence the other three issues as they underpin behavior and communication, but they might be more easily adaptable or subject to compromise compared to the concrete barrier that language can present.
