HC Deb 14 November 1968 vol 773 c123W
48. Mr. Gordon Campbell

asked the Postmaster-General to what extent telephone subscribers are being asked general knowledge questions in connection with checking faults in the telephone system; and if he will make a statement.

Mr. Stonehouse

In connection with research into human factors in the use of the telephone, a small sample of the population has been interviewed by a market research organisation. As is usual in surveys of this character a few general questions were included.
