COMMENTARY ON A PAPER BY WISEMAN, SMITH AND MILTON ON THE 'PSYCHIC PET' PHENOMENON
by RUPERT SHELDRAKE
In August 1998 the British Journal of Psychology published a
paper entitled 'Can animals detect when their owners are returning home?
An experimental test of the "psychic pet" phenomenon' by Richard Wiseman,
Matthew Smith and Julie Milton. This paper was widely publicized thanks
to a media release issued by the Press Office of the British Psychological
Society. The sceptical tone of this announcement, entitled 'Mystic dog
fails to give scientists a lead', was reflected in the ensuing newspaper
reports: 'Pets have no sixth sense, say scientists' (The Independent
, Aug 21); '"Psychic" dog is no more than a chancer' (The Times
, Aug 21); 'Psychic pets are exposed as a myth' (The Daily Telegraph
, Aug 22). The wire services reported
the story world-wide.
Together with Pamela Smart, I
have carried out over 200 experiments with the dog in question, called
Jaytee. The four experiments that form the basis of the paper by Wiseman
and his colleagues were carried out at my invitation (and with the loan
of my video equipment). I would like to take this opportunity of putting
into context their paper and the publicity it excited.
Many dog owners claim that their
animals seem to know when a member of the household is coming home, showing
their anticipation by waiting at a door or window. Some dogs are said to
react more than 10 minutes in advance (Sheldrake & Smart, 1997; Brown
& Sheldrake, 1998; Sheldrake, Lawlor & Turney, 1998). In 1994 I
proposed a simple experiment to investigate this claim (Sheldrake, 1994):
the owner should come home at a non-routine time in an unfamiliar vehicle,
such as a taxi, and the people at home should not know when the person
is coming. Does the dog still show its usual signs of anticipation? Or
is this phenomenon merely a matter of routine, selective memory, subtle
cues from people at home, or hearing a familiar vehicle approaching?
In an initial series of 100 observations
on Jaytee's behaviour during the absences of his owner, Pamela Smart (PS),
on most occasions he began waiting around the time that PS set off to come
home, at whatever time of day, or by whatever means of transport. He did
so when PS returned at randomly chosen times unknown to the people at home
with the dog (Sheldrake & Smart, 1998). However on 14 out of 100 occasions
he did not show this anticipatory behaviour. On some of these occasions
he appeared to be distracted by a bitch on heat in a neighbouring flat,
on others he was sick, but sometimes he failed to wait at the window for
no apparent reason. Nevertheless, taking all the data into account there
was a highly significant relationship (p<0.0001) between the time that
the dog began to wait at the window and the time his owner set off to come
home (Sheldrake & Smart, 1998).
In November 1994, the Science
Unit of Austrian State Television (ORF) filmed an experiment in which PS
went out, leaving Jaytee in her parents' flat. PS was then asked to come
home at a randomly-selected time. Her parents and the cameraman filming
the dog in their flat did not know when she would be returning. She travelled
by taxi. In this experiment, Jaytee got up and went to wait at the window
11 seconds after PS was told to go home, and he stayed there throughout
her 15-minute homeward journey.
Richard Wiseman, well known in
the media for his sceptical views, was asked by various newspapers and
television programmes for his comments on Jaytee's anticipatory behaviour.
He suggested a number of possible explanations, such as routine times of
return and selective memory, which I had already tested and eliminated.
I invited him to do his own tests, and PS and her family kindly agreed
to help him.
Wiseman did four experiments with
the help of his assistant Matthew Smith. In these experiments the behaviour
of the dog was videotaped continuously by Wiseman throughout PS's absence,
with the timecode recorded on the film. Meanwhile, PS travelled with Smith
to locations 5.5 to 8 miles away, and later set off home with Smith at
randomly-selected times known in advance to Smith but not to herself. They
returned in cars with which Jaytee was unfamiliar, to avoid any possible
sensory clues from familiar vehicles. Wiseman and PS's parents did not
know when PS would be returning.
As in many of my own experiments,
in the 3 tests conducted at the home of PS's parents, the dog sometimes
went to the window when PS was not returning, for example to watch other
dogs walking past or cars pulling up outside. But he waited there much
more when she was on her way home (Figure 1). My own videotaped experiments
show a very similar pattern (Sheldrake, 1999).
In these graphs the time over
which the experiment took place is divided into 10-minute periods. The
final 10-minute period on each graph represents the first 10 minutes of
PS's return journey, while she was still too far away from home for Jaytee
to detect the approach of the car. This car was in any case unknown to
him.
Wiseman, Smith and Milton's
criterion for Jaytee's success or failure
Instead of plotting their data
on graphs and looking at the overall pattern, Wiseman, Smith and Milton
used a criterion of their own invention to judge Jaytee's 'success' or
'failure'. They did not discuss this criterion with me, but based it on
oversimplified remarks about Jaytee's behaviour made by commentators on
two British television programmes which re-broadcast an extract from the
ORF experiment (Wiseman, Smith & Milton, 1998). These television programmes
stated that Jaytee went to the window every time that his owner
was coming home. In fact, he did so on 86 per cent of the occasions (Sheldrake
& Smart, 1998). And on one of these programmes it was said that Jaytee
went to the window "when his owner Pam Smart starts her journey home."
In fact Jaytee often went to the window a few minutes before PS
started her journey, while she was preparing to set off (Sheldrake &
Smart, 1998).
Wiseman et al. took Jaytee's 'signal'
for his owner's return to be the dog's first visit to the window for no
apparent external reason. In the first experiment this 'signal' lasted
for 53 seconds. In their paper, they remark that when viewing this videotape,
PS correctly remarked that Jaytee
only stayed at the porch for a fairly brief period of time.... and that
a better indicator of his signal might be when he remained there for a
longer period of time. For this reason the authors decided that any future
study should not take the first time that he inexplicably went to
the porch as his 'signal' but, instead, the first time that he inexplicably
visited the porch for more than 2 minutes. [their italics]
The following experiments were judged
according to this new criterion. Wiseman et al. found that Jaytee reacted
according to their arbitrary criteria in all three experiments at PS's
parents flat before PS set off at the randomly-selected time. These
experiments were therefore classified as failures. They ignored the dog's
behaviour after the 'signal' had been given.
In addition to these experiments
at PS's parents' flat, they carried out a test at the house of PS's sister,
where Jaytee had to balance on the back of a sofa to look out of the window.
In the Wiseman-Smith experiment in this house, the first time he visited
the window for no apparent reason coincided exactly with PS setting off,
and her sister remarked at the time, on camera, that this was how Jaytee
behaved when PS was coming home. But Jaytee did not stay there for long
because he was sick; he left the window and vomited. Because he did not
meet the two-minute criterion, this experiment was also classified as a
failure.
The negative conclusions of Wiseman,
Smith and Milton are unjustified for at least four reasons:
1. When PS was on her way home,
Jaytee's characteristic behaviour, as noted by the Smart family and documented
in my own experiments, was his waiting by the window. This pattern can
be seen by looking at all the data (as in Figure 1) rather than by confining
attention to an arbitrarily brief period. Wiseman et al. correctly point
out that pet owners could draw false conclusions about an animal's 'signal'
if they considered only one of the possible signals and ignored others;
they rightly emphasize the need for 'a complete and accurate recording
of the pet's behaviour.' But having made such a record, they then disregard
it in favour of a single 'signal' - a 'signal' defined by themselves on
the basis of a remark on a television programme.
2. Jaytee's 'signal' for PS's
return was supposed to be a visit to the window for an inexplicable reason,
i.e. for a reason that was not apparent on the videotape itself. Nevertheless,
Jaytee's attention might have been attracted to incidents outdoors that
were not visible in the narrow field of view of the camera, and hence an
explicable visit could be wrongly classified as 'inexplicable'.
3. In so far as the purpose of these
experiments was test the possibility that Jaytee was capable of responding telepathically
to PS's intentions to come home, the experimental design involved a serious
flaw. Wiseman et al. assumed that PS, waiting with Smith in a pub or other location,
would not think about returning until Smith told her to. In fact, she tells
me that as time went on she could not help thinking about going home, with thoughts
like "It won't be long now". In all three experiments conducted in PS's parents
flat, the randomly-selected return times were in the second half of the experimental
period, and PS knew that they would have to be leaving by the end of this period.
Moreover, while they were waiting together, Smith knew when they would be setting
off, and he could well have communicated his anticipation to PS unconsciously
through subtle cues, such as glances at his watch. Hence the tendency of Jaytee
to go to the window before PS set off (Figure 1) could have reflected her own
anticipation that she would soon be leaving.

Figure 1. Results
of the three experiments carried out by Wiseman and Smith with Jaytee
at PS's parents' flat on June 12, 1995 (A); June 13, 1995 (B); and December
4, 1995 (C). The graphs show the total amount of time that the dog spent
at the window in successive 10-minute periods. The 10-minute periods were
defined in relation to the randomly-selected time at which PS was told
to return home. The final point on each graph represents the first 10
minutes of PS's return journey, and is indicated by a filled circle (
-o- ). PS's return journeys took 20 minutes, 11 minutes and 13 minutes
in experiments A, B and C respectively. Any visits to the window that
Jaytee may have made in response to the car's approach and PS's arrival
have therefore been excluded. The time in each experiment when the dog
gave its 'signal', as defined by Wiseman, Smith and Milton, is indicated
by an arrow

4. The data of Wiseman et al. show the
same pattern of response as my own (Sheldrake, 1999) and hence confirm rather
than refute my findings about Jaytee's anticipatory behaviour.
Publicizing a sceptical claim
In the summer of 1996, while I
was continuing a long series of videotaped experiments with Jaytee, Richard
Wiseman went to several international conferences, including the World
Skeptics Congress, and gave lectures about the 4 experiments he and Smith
had done with this dog, stating that the dog had failed their tests. For
one of these conferences they wrote a paper (Wiseman & Smith, 1996)
very similar to the paper published in the British Journal of Psychology
(with the addition of Milton as an author), and sent me a copy.
In September 1996, Wiseman and
I met to discuss these findings. He raised objections to the way I had
plotted the data on graphs, and suggested an improved method, dividing
up the experimental period into 10-minutes intervals. The graphs shown
here (Figure 1) use this method suggested by Wiseman. I sent copies of
these graphs to him before he and his co-authors submitted their paper
to the British Journal of Psychology and suggested that they draw
attention to the fact that the dog spent most time at the window while
PS was actually on her way home. But they did not mention this striking
effect either in their paper or when they publicized their sceptical conclusions.
Over the next two years, Wiseman
announced repeatedly through the media that he had discredited this dog's
ability to anticipate his owner's return. For example, on a British television
programme called Strange But True (ITV; 1 November, 1996) he said
of Jaytee: 'In one out of four experiments he responded at the correct
time - not a very impressive hit rate and it could just be coincidence'.
The three 'misses' are the experiments summarized in Figure 1.
On another British television
programme called Secrets of the Psychics (Equinox, Channel
4; 24 August, 1997) he and several fellow sceptics debunked a series of
bogus seances and fraudulent healers and in this context he said of Jaytee:
We filmed him continuously over
a three hour period and at one point we had the owner randomly think about
returning home from a remote location and yes, indeed, Jaytee was at the
window at that point. What our videotape showed, though, was that Jaytee
was visiting the window about once every 10 minutes and so under those
conditions it is not surprising he was there when his owner was thinking
of returning home.
In order to support this statement,
a series of video clips showed Jaytee going to the window over and over
again, eight times in all. The times of these visits to the window can
be read from the timecode. They were taken from the experiment on shown
in Figure 1A. Two of these eight visits were the same visit shown twice,
and three took place while PS was on the way home, although they were misleadingly
portrayed as random events unrelated to her return.
The British Psychological Society's
Press Office helped Wiseman's sceptical claims to reach a yet wider audience,
and a quote from Wiseman included in their media release was widely reported
in the press: 'A lot of people think their pet might have psychic abilities
but when we put it to the test, what's going on is normal not paranormal.'
Smith was quoted as saying: 'We tried the best we could to capture the
ability and we didn't find any evidence to support it' (Irwin, 1998).
Wiseman, Smith and Milton have
succeeded in proving that the media can be misleading. They have also shown
that the claims of sceptics need to be treated with scepticism. But in
spite of their polemical intentions, their data support rather than refute
the idea that some dogs anticipate their owner's returns, whatever the
explanation for this ability may turn out to be.
