That statement is False.
MAslow hierarchy of needs depict a clear path which indicates that people wouldn't be able to fulfill the needs on higher hierarchy if we haven't fulfill the needs on lower hierarchy.
Here's his hierarchy's arrangement from top to bottom:
- self actualization
- Self-esteem
- Love/belonging
- safety
- Physiological
But often times, we do not follow this hierarchy from bottom to top. (for example, some obsessed individual might want to sacrifice need for love/belonging as long as she could realized her life-long dream i.e: self-actualization)
