In order to proceed with our investigation of the language faculty with the general scientific method in (5) [=the hypothetico-deductive method, HH], we must ensure the following, at least to a minimally satisfactory degree.

(6)a.It is possible to compute the consequences of the "guess."
b.It is possible to determine whether or not the consequences of the "guess" agree with the observations and/or the experimental results.

(6a) and (6b) can in turn be ensured only if (7) and (8) hold, respectively.

(7)The "guess" is part of, or is related to, a larger deductive system.

(8)The consequences of the "guess" are related, ultimately, to something 'observable/measurable'.

Furthermore, we should like to ensure (9) as best as we can.

(9)Disagreement between the consequences of the "guess" on the one hand and the observations and/or the experimental results on the other could lead us to learn something about the language faculty.

The proposal put forth in Hoji 2009 is an attempt to ensure these.

My current work share most of the above. Both Hoji 2009 and my current work emphasizes the importance of:

-deducibility
-testability, reproducibility
-maximizing the significance of experimental results

(9) above was addressed in Hoji 2009 under the "Maximizing our chances of learning from errors" heuristics, but that heuristic is understood now as being subsumed under the "Maximize the significance of experimental results" heuristics.
