appraisal is the determination of who ben-
efits and who bears the costs and risks in-
volved in a project. In recent years a vari-
ant of CBA known as risk-benefit analysis
(RBA) has evolved for use in cases where
the assessment of risk is a key component.
Methodologically, it has much in common
with CBA, although, as its name implies,
the emphasis on risk assessment tends to
be more pronounced.
Personally, I have always been a firm be-
liever in the merits of openness in govern-
ment. I hope the methods I’ve described
indicate one way in which this can be
achieved where risk assessment is a key an-
alytical component in decision-making.

SOCIETAL HEALTH

As a medical doctor, I thank you for pub-

lishing the excellent commentary on

“What’s Missing from Medical Training,”

by Erin Paquette and Angira Patel [Forum,

March]. To help improve our public’s

health, I think we need more such articles

published, read and understood by a

greater number of people. Good-quality

health care does call for tackling health

problems at their roots. More providers

must go “upstream” to advocate for im-

proving fairness and equity in opportuni-

ties for better well-being through social

determinants of health in all aspects of so-

ciety. Not doing so leaves medical inter-

ventions unfinished and communities

frustrated—and will mean society cannot

reach its full capacity to thrive.

“Future Fossils,” by Rachel Nuwer [Ad-

vances], should have said that people and

livestock make up 96  percent of all mam-

mals’ biomass rather than 96  percent of

all mammals.

Andrea Gawrylewski’s review of The

Human Planet [Recommended] should

have referred to the South Pole rather than

the southern tip of Antarctica.

“Landing on the Right Foot,” by Leslie

Nemo [Advances, June], includes a map

illustration with an incorrect key. It

should have indicated that U.S. states

shown in blue use the “U.S. survey foot”

and that those set in pink use the “inter-

national foot.”
