3. ALGORITHMS TOO CAN BUILD (DIS)TRUST
Personalization represent a
challenge with 3 key
problems identified :
– Too much personalization
key information may be
missing
– Alternative viewpoints may
be absent
– Privacy may be threatened

4. 5 RULES TO MAKE ALGORITHMS MORE
ETHICAL
1. Avoid discrimination
2. Promote gender equity
3. Open up customers’
minds (exploration)
rather than trapping
them (exploitation)
4. Respect right of not
being tracked
5. Educate users on
algorithms
5. EDUCATION IS KEY
• Empower users: give
control back
• Build knowledge
• « Show » your algorithms
(open the black boxes !)
“An [algorithmic] system
that you can't audit is a
system that you can't use"
