  The LEP2 experiments pose a serious naturalness problem for supersymmetric
models. The problem is stronger in gauge mediation than in supergravity models.
Particular scenarios, like electroweak baryogenesis or gauge mediation with
light messengers, are strongly disfavoured. Searching a theoretical reason that
naturally explains why supersymmetry has not been found poses strong requests
on model building. If instead an unlikely (p\approx 5%) numerical accident has
hidden supersymmetry to LEP2, we compute the naturalness distribution of values
of allowed sparticle masses and supersymmetric loop effects. We find that b to
s gamma remains a very promising signal of minimal supersymmetry even if there
is now a 20% (4%) probability that coloured particles are heavier than 1 TeV (3
TeV). We study how much other effects are expected to be detectable.
