[The ‘fisherman_3c’ is the perspective level.

The ‘hook_3a’ is the thought experiment.

Yes, even psychologists are ‘fishers of ‘men”.

Yet, they know not what they do.]

[Sensible construction is characteristic of the social sciences.

In sensible construction, the perspective level is never challenged (unless, of course, something breaks).]

[The subject is not aware of the experimentalist’s perspective.

Often, neither is the investigator.

This lack of awareness does not fit the label ‘bias’.

All surveys share the same relational structure. Even a researcher who carefully tries to eliminate biases cannot eliminate this feature.]

Summary of text [comment] pages 86 and 87

[How is the psychological experiment, say a survey, like fishing?

Every something_2a, that emerges from and situates the potential of the subject under investigation_1b, has a hook to a thought experiment_3a. That thought experiment_3a reflects a perspective_c.]

[Consider the discipline of experimental psychology.

Every psychological experiment where the subject chooses something exhibits this two-level interscope.

The experiment investigates the situational nested form:

I, seat of choice_3b( my choice_2b( potential of something_1b))

However, the experimentalists inject a perspective into the adjacent and lower level, as content.

The name ‘thought experiment_3a’ seems appropriate. Does it not?]
