What is the current state of the law on freedom of speech of qualified privilege?

In Horrocks v. Lowe, cited earlier, the court said this: ... indifference to the truth of what he publishes is not to be equated with carelessness, impulsiveness or irrationality in arriving at a positive belief that it is true. The freedom of speech protected by the law of qualified privilege may be availed of by all sorts and conditions of men. In affording to them immunity from suit if they have acted in good faith in compliance with a legal or moral duty or in protection of a legitimate interest the law must take them as it finds them. In ordinary life it is rare indeed for people to form their beliefs by a process of logical deduction from facts ascertained by a rigorous search for all available evidence and a judicious assessment of its probative value. In greater or in lesser degree according to their temperaments, their training, their intelligence, they are swayed by prejudice, rely on intuition instead of reasoning, leap to conclusions on inadequate evidence and fail to recognise the cogency of material which might cast doubt on the validity of the conclusions they reach. But despite the imperfection of the mental process by which the belief is arrived at it may still be “honest” that is, a positive belief that the conclusions they have reached are true. The law demands no more. p. 13
