Plaintiff is a veteran of the First World War. He is insured against total permanent disability under the War Risk Insurance Act.1 In a prior action under this contract,2 a jury found that he became totally permanently disabled on April 5, 1919 and that the disability continued until the date of entry of judgment, April 11, 1929. Later, acting pursuant to an authorized3 regulation,4 the Administrator of Veterans’ Affairs ordered the monthly payments halted July 4, 1934. because he found that total disability had ended. On December 10, 1934 plaintiff-veteran brought an action to recover disability which accrued subsequent to July 4, 1934. The jury brought in a verdict for the plaintiff and the Government now appeals. It alleges as error that portion of the charge to the jury relating to burden of proof. The learned District Judge instructed as follows : “The burden of proof here is upon the Government to satisfy you by its fair weight that from July 4, 1934, to the present time, the plaintiff, Charles Anderson, was not permanently and totally disabled. * * * The condition of the plaintiff prior to July 4, 1934, is presumed to continue until the defendant satisfies the burden of establishing that it is not. * * * The burden is upon the defendant to show a change in the physical condition of the plaintiff prior to July 4, 1934 and by the fair preponderance of the evidence must overcome the presumption of total and permanent disability, as judicially determined in this court prior to July 4, 1934. * * * The defendant must establish by the fair preponderance of the evidence that the plaintiff, Charles Anderson, has recovered from the condition which prior to July 4, 1934, had been adjudged to constitute total and permanent disability. * * * ” Appellant’s Appendix, pp. 9, 10, 12, and 13.
It is agreed that in the absence of the prior judgment of April 11, 1929 the burden would be upon the insured to establish by substantial evidence that his disability was total and that it was reasonably certain • that such impairment would continue throughout his life.5 The Government contends that the prior adjudication can in no way shift this burden of proof from the insured. The basis for the argument rests on precedents holding that a verdict of present total disability will not justify the entry of *171judgment for installments to accrue in the future6 and that a verdict may not be used as res judicata in a subsequent action for future installments.7 From these rulings the Government would draw the conclusion that the prior judgment can be given no future effect at all. This conclusion, however, is too broad. While a verdict permitting recovery under the War Risk Insurance Act cannot settle the question of future disability, it must contain a finding that the presently existing disability has a reasonable certainty of continuing.8 This finding cannot be ignored in future controversies. From it is born a presumption based upon the reasonable certainty of the continuance of the condition.9
Professors Thayer10 and Wigmore11 have asserted that a presumption may never shift the burden of proof. It is their position that a presumption may alter the burden of going forward with the evidence but it can have no effect upon the burden of persuasion. Dazzled perhaps by the scholarship of these gentlemen, other commentators have accepted their views.12 A reconciliation of decisions which refused to follow the pattern has even been attempted by arguing that presumptions which do result in a shifting of the burden of proof are not “true presumptions.”13
A few commentators, however, have undertaken an independent analysis of the authorities.14 It is their conclusion that the effect of a presumption is to be measured by the reasons for its use. The presumption which concerns us here is that of persistency in time. Professor Wigmore states its logic in this manner:
“When the existence of an object, condition, quality, or tendency at a given time is in issue, the prior existence of it is in human experience some indication of its probable persistence or continuance at a later period.
“The degree of probability of this continuance depends on the chances of intervening circumstances having occurred to bring the existence to an end. The possibility of such circumstances will depend almost entirely on the nature of the specific thing whose existence is in issue and the particular circumstances affecting it in the case in hand. That a soap-bubble was in existence half-an hour ago affords no inference at all that it is in existence now; that Mt. Everest was in existence ten years ago is strong evidence that it exists yet; whether the fact of a tree’s existence a year ago will indicate its continued existence to-day will vary according to the nature of the tree and the conditions of life in the region. So far, then, as the interval of time is concerned, no *172fixed rule can be laid down; the nature of the thing and the circumstances of the particular case must control.”
2 Wigmore on Evidence, 3d Ed., § 437, p. 413.
But logic is not the sole basis for the presumption. Public policy also lends its support. Absent the presumption, the Government’s power would be supreme. It could cut off the disability payments as frequently as it desired, and so cast upon the unfortunate insured the burden of proving his disability on each occasion. Where a presumption is based upon both the balance of probabilities and considerations of policy it should shift the burden of proof.15 As Professor Morgan has said:
“A great number of recognized presumptions express the normal balance of probability. * * * The party against whom the presumption operates is relying upon the existence of the unusual, and this might well require him to make it appear more probable than not; this is, to produce a preponderance of evidence. In the absence of other factors pertinent to the allocation of the burden of persuasion, why should not the trier whose mind is in equilibrium be required to find for the usual rather than the unusual? * * *
“The conclusion, then, is that the oft-repeated formulae of the courts respecting presumptions should be scrapped, and presumptions should be classified according to the reasons which justify their creation and existence. Those reasons should determine their procedural consequence. The narrowest class would consist of those expressing a mere balance of probability and' containing some counteracting elements of inconvenience or policy. These should require only the production of evidence sufficient to avoid a directed verdict. All others should fix at least the burden of producing evidence actually credited by the jury which would justify a reasonable jury in finding against the presumption. The following classes should determine the burden of persuasion also: (1) those expressing the balance of probability and containing no elements of inconvenience or policy which, aside from the presumption, would normally fix the burden of persuasion on the other side. (2) Those founded upon considerations of comparative convenience in producing evidence and involving no countervailing considerations of policy. (3) Those created to further a result judicially deemed socially desirable. (4) Those supported by two or more of the foregoing considerations.”

The cited decisions are in accord16 although it is only fair to say that they do not give us the benefit of much reasoning.
The judgment of the District Court is affirmed.
