Is it always wise for you to observe the obverse of things as well?

Not always. looking up at an open sewage pipe have dangers that can be avoided by moving to another location where you can look at it sideways.

Always is a slippery slope indeed.

Most of the time is a safer bet.

I think looking at things from as many angles as possible, including the obverse, is usually very helpful.

Consider politics. I can almost hear the groan.
Let's say I'm a liberal (actually I'm a Green.) If I'm an elected representative and sitting in opposition to the government, I may still have a chance of either blocking or negotiating for amendments to proposed legislation. If I have a thorough understanding of my opponents' goals, values, and motives, I stand a far better chance of being able to propose workable solutions that may be acceptable to the conservatives. If I do this, I'm doing my best to represent my constituents and doing a better job of working within the framework of democracy. If I don't examine the issues thoroughly from all angles, I strangle my ability to achieve anything.

The obverse is logically equivalent to the original proposition.
