Viewing a problem "through a different lens" is least likely accomplished by looking at the problem:

Viewing a problem "through a different lens" involves analyzing it from various perspectives to gain new insights and understanding. This is often achieved by considering the problem from alternative viewpoints, contextualizing it differently, and imagining how the situation could change under different scenarios.

When one looks at a problem with different objectives, it may entail approaching it with the same fundamental framework or goal in mind. This can limit the range of insights that can be derived, as the core objective may constrict the view of potential solutions or alternatives available. On the other hand, exploring the problem from a different point of view, in a different context, or under varying circumstances encourages a more comprehensive analysis, enabling the identification of novel solutions and fresh perspectives.

Thus, while changing objectives is important, it does not inherently facilitate viewing the problem through a new lens as effectively as the other options that promote broader shifts in perspective.
