Recall, however, that such inductive considerations form only part of the overall evidence which can be cited in favor of \(\textbf{P} \neq \textbf{NP}\). In particular, various heuristic considerations also point to the non-coincidence of the classes \(\textbf{NP}\) and \(\textbf{coNP}\) and of \(\textbf{PH}\) and \(\textbf{PSPACE}\), and hence to positive answers for Open Questions 2 and 3. But were it to be the case that \(\textbf{P} = \textbf{NP}\), then these questions would be resolved negatively in a manner which runs strongly counter to our current expectations (see Sections   3.4.1 and 3.4.2).
