It feels obvious that optimism and pessimism sit at opposite ends of one line — more of one means less of the other. The factor analyses keep disagreeing, and they have been disagreeing for thirty years.
Quick Answer: Positively and negatively worded optimism items load onto separate factors often enough that many researchers report two scores instead of one. Herzberg, Glaesmer and Hoyer (2006) found a two-factor solution fit better than a single dimension in a large general-population sample. The practical consequence: you can be high on both or low on both, and a single total hides which half produced it.
The Finding That Will Not Go Away
When researchers factor-analyse optimism scales, the positively worded items ("I expect the best") tend to cluster together, and the negatively worded ones ("I rarely count on good things happening") cluster separately.
The first response was that this must be an artefact — a known statistical quirk where item wording creates a fake factor. Then it kept appearing, in different samples, in different languages, on different instruments. Herzberg and colleagues tested it directly on the revised Life Orientation Test in a large general-population sample and reported that the two-factor model fit better than treating the items as one dimension.
Two people with the same optimism total can be almost nothing alike — one hopeful and unsteady, the other settled and modest in what they expect.
What Being High on Both Looks Like
Someone who expects a specific project to go well while also believing that difficulties are everywhere is not confused. They are holding two separable judgements: one about a goal, one about the terrain.
In practice this is a common profile in people who have shipped things. They expect to succeed because they have before, and they expect obstacles because they have met them. Forcing that onto a single line loses the more informative half of the picture.
What Being Low on Both Looks Like
The mirror profile is flatter — neither strong expectation of good outcomes nor strong expectation of bad ones. It reads as detachment more than gloom, and it can accompany a period where outcomes have simply stopped feeling connected to effort.
A single-score scale places this person in the middle band alongside someone with genuinely balanced expectations, which are two different states with the same number attached.
How This Test Handles It
- One overall band for where the balance landed, on a five-level scale from Braced for the Worst to Strongly Optimistic.
- Positive Outlook — the items about expecting good things, looking on the bright side, and expecting to succeed.
- Emotional Steadiness — the items about baseline mood and self-regard, which is where much of the negatively worded variance lives.
- The gap between the two is the reading a single number cannot give you, in either direction.
Which Number Should You Read?
The gap, more than either subscale on its own. A wide gap is the informative result, because it identifies which half of your outlook is doing the work.
High expectations with a low steadiness score suggests hope carried on an unsteady base — the person who believes it will work out and feels bad most of the way there. The reverse suggests someone settled in themselves who simply does not assume good outcomes, which is a very different thing from being unhappy.
See Your Own Split
The Optimism and Pessimism test reports both subscales alongside the overall band. For the neighbouring measures, the Self-Esteem test covers the self-regard items in more depth, and the Perceived Stress Scale reads current pressure rather than general outlook.
