"Involve" is the correct choice. Statements that purport to be always true are typically phrased in the simple present.

Roses have a lovely smell

implies neither that they stunk in the past nor that they will stink in the future.

"Involve" and "include" have overlapping fields of meaning, but the primary meaning of "involve" implies "be a participant" in some act or process whereas "include" may imply no more than to "be a member" and so has a less active implication. Thus, "involve" is better in this case because consideration of alternatives is a process rather than a state.

In this context ' involve' is the right answer,as it logically agrees with its plural subject ---- 'Most decisions'.
