  “Institutional support” Institutional support means resources or official encouragement provided by institutions. For example, a university might support a research area through: establishing a research center, hiring professors specializing in it, funding research assistants, offering grants, organizing conferences, creating courses, providing laboratory/archive resources. Thus: “Which research areas receive institutional support?” means: Which areas receive organizational resources and encouragement that make research in those areas easier to conduct and publish?

  “Correlated with an institutional or ideological structure” Suppose you discover that: a certain interpretation repeatedly receives funding, competing interpretations repeatedly lose funding, university curricula repeatedly favor one interpretation, publishers repeatedly reject the alternative, and these patterns occur across many institutions. If these patterns consistently correspond with a particular ideological or institutional structure, you may have evidence that the structure is related to the scholarly outcome . That is much stronger than simply saying: “Scholar X wasn't cited.” Then you have evidence about how the scholarly system operates , rather than merely about one scholar's citation count.

  Absence of evidence I make an important distinction here. The statement: “The theory is supported because there is no evidence against it” is not logically justified merely from the absence of contradictory evidence. Why? Because no contradictory evidence could mean several things: the theory is true; nobody has looked carefully; relevant evidence was destroyed; relevant records never existed; the evidence exists but has not been discovered. So absence of contrary evidence does not itself establish truth. My second statement “The theory is unsupported because there is no evidence for it.” That is also different from saying it is false. It means: We currently lack evidence sufficient to support it. So your formulation is correct: The proposition remains unresolved pending adequate evidence. Why ask what evidence should reasonably exist? Suppose someone claims: “Lincoln secretly intended X.” If that were true, we might reasonably expect some evidence in: correspondence, private not...

  Intellectual fashion and “not mutually exclusive” Intellectual fashion A scholarly field may concentrate on certain questions because they are currently regarded as especially important. For example: During one period, historians may emphasize class. Later: gender becomes especially prominent. Later: race, empire, environment, or global history may become dominant. A researcher working outside the current emphasis may receive less attention. “Not mutually exclusive” It means: Both or several explanations can be true at the same time. For example, a neglected historian could be overlooked because of: language barriers and institutional prestige and intellectual fashion. You don't have to choose only one.

 terminology point: “Evidential support” is clearer than “independent support” when independence is not actually being established. “Independent evidence” is appropriate only when the evidence is genuinely independent of the proposition being tested.

  “Rescuing the theory” It is not inherently wrong to introduce a new explanation after contradictory evidence appears. A scientist or historian may legitimately discover a new factor because the evidence reveals something previously unknown. The problem arises when: a contradiction appears; an explanation is invented solely to prevent the theory from failing; the explanation has no evidence of its own; every subsequent contradiction produces another ad hoc explanation. So the problem is not the timing alone. The problem is unsupported auxiliary explanations introduced merely to immunize the theory against contrary evidence.

  “The evidence does not merely derive from the same assumption” Suppose you argue: Theory: capitalism expands when labor becomes mobile. Then you say: “We know labor became mobile because capitalism expanded.” That is circular. You are using the conclusion to prove the premise. Instead, use evidence independent of the conclusion: Census data show workers moving from rural areas to industrial cities. Now you have evidence of mobility independently of the proposition that capitalism expanded.
