Brain-power

THE LANCETLONDON: SATURDAY, DEO. 28, 1946

THE present man-power shortage is particularlyacute in the professions and the upper ranks of indus-try, commerce, and the public service. This state ofaffairs is due partly to the seven years’ gap in recruit-ment to some callings and partly to reduction in thenumber of university students during the war ; butit derives also from greater efforts to make industryefficient and to develop the social services. In theirlatest broadsheet 1 P.E.P. estimate that ideally theannual intake to the professions should exceed the pre-war level by 80% in 1946-50, and by 55% in 1951-55.For the next ten years teaching alone will need 23,000recruits a year ; and there ought to be substantialincreases in the number of nurses, scientists, dentists,social workers, and medical auxiliaries. The BarlowCommittee has advised that the annual output ofpure scientists should be twice the pre-war total of2500 ; and there should be about the same increasein technologists. According to the Teviot Committee,the annual output of dentists, which was 340 beforethe war, should be raised to 800 as soon as possible.By comparison, the medical profession is well served:the Goodenough Committee’s 1944 estimate was thata 20% increment would be enough ; and the committeeheld that this could be achieved in six years by a15% increase on the pre-war annual output of 2000doctors. Professions in which the pre-war intake willsuffice, after the war-time fall-in recruitment has beenmade good, include accountants, company secre-

taries, and librarians. Those in which present numbersare enough comprise opticians, pharmacists, and

possibly also solicitors. ’

Nobody can say how much demand there will be foruniversity graduates in arts, but P.E.P. suggest thatin order to balance the tendency towards specialisa-tion more young men and women should study thehumanities. The risk of encouraging them to takean arts degree is that those who are not absorbedelsewhere may reluctantly turn their hand to teaching,with unhappy results for themselves and for that

profession. Much of course will depend on industry’sliking for men and women with university qualifica-tions. Owing to the replacement of smaller under-takings by large ones, managers are now usuallyappointed on their merits, and it has become unusualfor a firm to recruit its senior staff in their teens.The Cambridge University Appointments Boardfound that 73% of employers favour a preliminaryuniversity education, because it induces an indepen-dent and critical outlook, capacity for responsibility,and social ease. With opportunities for higher educa-tion depending more and more on ability, rather thanon the parents’ capacity to pay, industry may in anycase have to look to the universities if it wants brains.Recruitment to the professions and administration

should be planned with three aims : the recruits shouldbe of high quality; the supply should be adjusted to1. Britain’s Need for Brainpower, Planning, no. 259: obtainable

the demand ; and there should be fair distributionbetween the various callings. All this can best beachieved by offering advice and information aboutcareers ; by financial aid for suitable people whocannot meet the cost of education ; by improvingmethods of, selection; by balancing salaries andconditions between the major callings; and bytapping all sources. Perhaps only the Governmentcan give wide enough publicity to training and pros-pects of employment; but the Ministry of Labourhas not yet taken the steps to issue " reports ontrends of employment in relation to higher appoint-ments " which the Hankey Committee recommended.An annual Government prediction, imperfect thoughit might be, could be no wider of the mark than thatof parents who act on rumours of excellent prospectsin some particular profession. If the best recruits are

to be secured, the opportunity for training must dependsolely on ability ; and the P.E.P. report urges thatselection should be both by intelligence, as judged bywritten examination, and by character, as assessed byinterview, some university scholarships being awardedfor outstanding personal qualities combined with goodintelligence. Factors influencing the intake of recruitsto the various callings include the financial rewards,the prospects of promotion, and the conditions ofservice ; but happily there are also other incentives-.the interest of the work, the sense of purpose it

bestows, the esteem in which it is held, and the scopeit offers for initiative and responsibility. These con-siderations, which do not weigh equally with all youngmen and women, must be reviewed in occupationswhere entrants are too few or of poor quality. Thusthe McNair Committee recommended an increase insalaries and improvement in the status of teachers,and the Government have lately taken action on similarlines in relation to the nursing profession. The TeviotCommittee reported that " dental appointmentsshould compare with those available to medical

personnel more favourably than they do at present, asregards status, remuneration, and opportunities."The P.E.P. survey underlines the urgency of

marshalling the country’s brain-power, including thatof the refugees now among us. In the final count,however, success will depend on the careful sieving ofthe nation’s youth, the training of all who are suitable,and a balanced allotment between occupations. Here,as in other tasks where resources are scanty, prioritiesmust be decided. Teachers in universities and schoolsshould, perhaps, come first, but other competingdemands are not easily settled : what, for example,of the rival calls for pure scientists and doctors ?It would be useful to have from time to time anestimate of the relative force of the various claims onour stock of trained intelligence.

Liver-function TestsTHE object of tests of liver function is twofold :

to express the extent of liver damage quantitatively,and to aid in the diagnosis between jaundice due toobstruction of large ducts and that due to a diffusehepatitis. The functions of the liver are many, andthe tests based on them are so numerous that theclinician may well wonder which will serve his purposebest. Until recently, evaluation of the tests was basedon findings obtained in typical examples of a givendisease. If these results were consistent, then similar
