One assumption for developing an integral metastudies approach to big picture research is that there are multiple lenses that have been used to develop those overarching schemas. All of these lenses need to be included in a comprehensive view of complex social realities. One of the most enduring of these lenses is the altitude lens. This lens looks at temporal complexity through the discourse of stage-based development.

Altitude lenses have been a common element of big pictures for many thousands of years. They typically map out some set of qualitatively different stages of growth and they propose that the changing nature of complex processes can be understood as a series of unfolding stage potentials. Altitude lenses come in a variety of forms, soft, hard, spiritual, cognitive, interpersonal, individual and collective but they all share this element of a vertical shift from one level to another. Wilber's levels, Spiral Dynamics colour stages, Fowler's stages of faith, Piaget's cognitive stages, all these are examples of the application of the altitude lens to various domains.

As with all lenses the altitude lens is subject to different kinds of truncations and reductionisms. I call these reductionisms the varieties of altitude sickness and, in a spirit of playful finger-pointing, I will briefly describe a few of these here:

1. Lens absolutism: This is the general problem of relying solely on one lens to explain vertical development.

2. Stagism: This is where all developmental capacity is thought to be function of the whole-of-system movement from one stage to another. This ignores the evidence that incremental learning and evolutionary process can result in transformative development.

3. Developmentalism: This is the view that transformative change is the result of changes in an individual's own structures rather than the structures that exist in their social and material surrounds.

4. Immediatism: This is the lack of awareness of the role of mediation in vertical development. For example relying on Piagetian models of structural change to the exclusion of Vygotskian ones.

5. Pigeon-hole(ism): This is the tendency for stage-based theorists to assume that those who are critical of stage-based models are relativists.

6. Vertical co-dependency (student variety): This is the assumption that only those at a higher stage can teach those from lower stages.

7. Vertical co-dependency (teacher variety): This is the assumption that those at a lower developmental stage need to be taught by those from a higher developmental level.

8. Communal altitudism: This is the assumption that a community of the adequate can only be constituted by those of requisite altitudinal level.

9. Individual altitudism: This is the view that you must know the altitude of your critic to judge whether their criticism is valid or not.

10. Altitude metricism: This is the seriously mistaken view that we need to be able to measure the altitude of individuals to be able to help them develop.

11. Lack of oxygenism: This is the syndrome of delusional symptoms that the human mind suffers from when it reaches a certain altitude.

12. Altitudinal fascism: This is the illness that besets a country when those who wish to take or maintain political power view all of its history in terms of the stage-based development of an elite group.

13. Altitudinal collectivism: This is the illness that besets a country when those who wish to take or maintain political power rationalise any action in terms of the stage-based development of the collective.

14. Altitudinal leaderism: This is the assumption that we need enlightened leaders to have enlightened communities.

There are many other varieties of altitude lens sickness. These are a few of the most damaging ones. They warn us that over-relying on any single lens for describing growth, development, evolution, progress, improvement, or advancement is dangerous. When they are closed to scientific criticism from any source, all forms of big picture research are susceptible to the many malaises that can infect meta-level studies.
