If the government increases its funding for civilian scientific research, private patrons and industries will believe that such research has become primarily the government’s responsibility.
Conclusion (Therefore)
In order to keep from depressing the overall level of funding for civilian scientific research, the government should not increase its own funding.
Evidence
If the government increases its funding for civilian scientific research, private patrons and industries will believe that such research has become primarily the government's responsibility.
If they believe that research is no longer primarily their responsibility, private patrons and industries will decrease their contributions toward research.
Evaluate
Since the two premises are both conditionals (if / when) and have an overlapping term, we should think about whether they chain together. They do, to form this chain:
Govt increases → Private ppl think → Private ppl own funding CS research not will decrease for CS research primarily their contributions responsibility to that research
A valid contrapositive conclusion to draw at this point would be,
The actual pseudo-contrapositive conclusion was,
Goal
Thus, the author is assuming this Missing Link:
.
The author is failing to consider that the increase in government funding might more than offset the decrease in private funding. The net effect could be equal or greater overall funding for CS research.
