B In many countries today such a scenario
is inconceivable. Researchers are not
allowed to offer significant sums of
money to participants in a medical trial.
even for ow-risk experiments. Offering
money
is
considered
'undue
inducement' that could interlere with a
'Volumeer's judgement on whether to
take part, and turn the relationship
between scientist and subject into a
commercial, unethical one.
C Benefits in kind like this are permissible,
and many volunteers receive them.
They are not considered undue
inducements, yet money is.. This is
paternalistic and nonsensical. It would
be far more respectful to volunteers if

researchers could offer them the cholce.
D Could you say that either situation

both cases they are effectively being
paid for taking on a greater risk. There
appears nothing objectionable in [heir
decisions, yet participants in medical

of just 10 US dollars ror completing an
anonymous qUe5tionnaire about their

hepatitis C.
H If (his is the case. surely it is only fair
tha t they share In the rewards? Publicly
funded research is perhaps more
complicated, as participants may be
acting in the public interest. Bul my
mam argument applies equally to
commercial and non-commercial trials:
researchers should be allowed fa pay
volunteers, and to pay them well. even
ror high-risk research.
