Feedback & Psychometric Summary

Gather what tests and other people say about you in one place, keep only what several sources agree on, and set it against your own rating. The gap between the two views is the finding worth acting on.

Big Five inventories rest on strong research (Goldberg, 1990; Soto, 2019). Type tools have weak or contested support: MBTI theory has been sharply criticized (Stein & Swan, 2019) and DISC has no peer-reviewed validation. Feedback from several sources has mixed evidence for changing performance (Smither, London & Reilly, 2005). The "two or more sources" rule is a rule of thumb.

Use it when:

• You have a recent review, 360 report or test result and want to know what to do with it.
• You have finished 1.2 Strengths & Weaknesses Grid and want an outside check.
• You are about to choose a development goal and want it to rest on more than your own view.

Skip it when:

• You have no outside input yet: ask for it first, using the phrases below, and come back with at least three sources.
• You want to plan the gaps you have already confirmed: use 1.5 Skill Gap Map & Priority List.

Self-knowledge needs outside data. How others experience you often differs from how you see yourself, and the gap between the two views is the finding worth acting on. The instruments you bring differ sharply in how far they can be trusted. Big Five inventories rest on a factor structure found again and again across instruments and observers (Goldberg, 1990; McCrae & Costa, 1987), and the trait view of leadership goes back to early reviews of personal factors in leaders (Stogdill, 1948). Type tools stand on weaker ground: the MBTI comes from Jungian typology (Jung, 1971; Myers, McCaulley, Quenk & Hammer, 1998) and its theory is openly contested, while DISC (Marston, 1928) lacks peer-reviewed validation. Any single source of feedback is noisy.

So every result here gets a line on what it tells you, the feedback is kept apart by source, and only themes that several people raise count as patterns. Comparing yourself with others shows blind spots and undervalued strengths, and you act on one of each.

Write the result and what it suggests you check in your feedback. A test describes tendencies, not how you perform.

Strong answer: "Big Five inventory, January: low extraversion. Suggests speaking up in large meetings takes deliberate effort; check whether my feedback shows it getting in the way." Not: "I'm an introvert, so I don't do big meetings."

Choosing an instrument: prefer instruments with published reliability and validity evidence. Big Five inventories (for example the BFI-2) have strong research support (Soto, 2019). Type tools such as the MBTI and DISC are popular, but MBTI theory has been sharply criticized (Stein & Swan, 2019) and DISC has little peer-reviewed validation, so treat type results as conversation starters, not evidence about how you perform. The instrument guide at the end of the page compares the common tools.

Illustrative example: the role, the company and all details are made up.

A finance manager at a ferry operator in Norway combines a Big Five inventory, last autumn's review and comments from peers and two analysts.

Section 1: high conscientiousness, low extraversion. To check: does being quiet in meetings hold him back?

Section 2: the manager praises reliability and wants shorter reports for senior management. Peers trust his numbers and find him slow to decide. The analysts value his teaching and want to present their own work. The skip-level says his budget proposal buried the main point under too many slides.

Section 3: strength pattern: accuracy, teaching. Development pattern: too much detail for senior readers; too cautious. Surprise: he thought doing the hard parts himself helped his analysts.

Section 4: leading others, self 4, others 3: a blind spot. Teaching, self 3, others higher: an undervalued strength.

Section 5: he offers a finance basics session for ship managers, writes every management report headline first, and asks his manager after each one whether the conclusion was clear on page one. His analysts present the next quarterly figures themselves.
