As a keen amateur photographer, I have come to value how lenses and filters enable different perspectives to be obtained. For example, to make clouds more distinct, I might use a polarising filter. In a different context, the same filter can reduce reflections but would serve little or no purpose capturing a night sky.
Careful selection of lenses and filters makes it possible to see things which might otherwise be lost, ignored or be taken for granted. Choosing the correct equipment requires skill and experience but can involve a degree of trial and error.
Personality tests are snapshots. They enable an individual to see themselves in different lights – in ways they might not have seen themselves before. Some focus on traits while others are based around personal preferences. Some are self-reports while others require the feedback of colleagues.
Just as the professional photographer requires a selection of lenses and filters, so we need a range of personality tests for different applications. I’ve posted previously about Maslow’s hammer so please check out why validity is an important consideration when it comes to selecting the most appropriate personality test.
